ACTN1
Alpha-actinin-1 is a protein that in humans is encoded by the ''ACTN1'' gene. Function Alpha actinins belong to the spectrin gene superfamily which represents a diverse group of cytoskeleton, cytoskeletal proteins, including the alpha and beta spectrins and dystrophins. Alpha-actinin-1 is an F-actin cross-linking protein – a bundling protein that is thought to anchor actin to a number of intracellular structures. Alpha-actinin-1 is a non-muscle cytoskeletal isoform found along microfilament bundles and adherens junction, adherens-type junctions, where it is involved in binding actin to the membrane. In contrast, skeletal, cardiac, and smooth muscle isoforms are localized to the sarcomere#Bands, Z-disc and analogous dense bodies, where they help anchor the myofibrillar actin filaments. Interactions Alpha-actinin-1 has been shown to Protein-protein interaction, interact with: * CDK5R1, * CDK5R2, * Collagen, type XVII, alpha 1, * GIPC1, * PDLIM1, * Protein kinase N1, * SSX2IP ...

Actinin
Actinin is a microfilament protein. The functional protein is an anti-parallel dimer, which cross-links the thin filaments in adjacent sarcomeres, and therefore coordinates contractions between sarcomeres in the horizontal axis. Alpha-actinin is a part of the spectrin superfamily. This superfamily is made of spectrin, dystrophin, and their homologous and isoforms. In non-muscle cells, it is found by the actin filaments and at the adhesion sites. The lattice like arrangement provides stability to the muscle contractile apparatus. Specifically, it helps bind actin filaments to the cell membrane. There is a binding site at each end of the rod and with bundles of actin filaments. The non-sarcomeric alpha-actinins, encoded by '' ACTN1'' and '' ACTN4'', are widely expressed. '' ACTN2'' expression is found in both cardiac and skeletal muscle, whereas ''ACTN3'' is limited to the latter. Both ends of the rod-shaped alpha-actinin dimer contain actin-binding domains.

GIPC1
GIPC PDZ domain containing family, member 1 (GIPC1) is a protein that in humans is encoded by the ''GIPC1'' gene. GIPC was originally identified as it binds specifically to the C terminus of RGS-GAIP, a protein involved in the regulation of G protein signaling. GIPC is an acronym for "GAIP Interacting Protein C-terminus". RGS proteins are "Regulators of G protein Signaling" and RGS-GAIP is a "GTPase Activator protein for Gαi/Gαq", which are two major subtypes of Gα proteins. The human GIPC1 molecule is 333 amino acids or about 36 kDa in molecular size and consists of a central PDZ domain, a compact protein module which mediates specific protein-protein interactions. The RGS-GAIP protein interacts with this domain and many other proteins interact here or at other parts of the GIPC1 molecule. As a result, GIPC1 was independently discovered by several other groups and has a variety of alternate names, including synectin, C19orf3, RGS19IP1 and others. The GIPC1 gene family in m ...

CDK5R2
Cyclin-dependent kinase 5 activator 2 is an enzyme that in humans is encoded by the ''CDK5R2'' gene. The protein encoded by this gene is a neuron-specific activator of CDK5 kinase. It associates with CDK5 to form an active kinase. This protein and neuron-specific CDK5 activator CDK5R1/p39NCK5A both share limited similarity to cyclins, and thus may define a distinct family of cyclin-dependent kinase Cyclin-dependent kinases (CDKs) are a predominant group of serine/threonine protein kinases involved in the regulation of the cell cycle and its progression, ensuring the integrity and functionality of cellular machinery.

PTPRT
Receptor-type tyrosine-protein phosphatase T is an enzyme that in humans is encoded by the ''PTPRT'' gene. PTPRT is also known as PTPrho, PTPρ and human accelerated region 9. The human accelerated regions are 49 regions of the human genome that are conserved among vertebrates, but in humans show significant distinction from other vertebrates. This region may, therefore, have played a key role in differentiating humans from apes. Function The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. PTPrho has been proposed to function during development of the nervous system and as a tumor suppressor in cancer. Structure This PTP possesses an extracellular region, a single transmembrane region, and two tandem intracellular catalytic domains, and thus represents a recept ...

Zyxin
ZYX is a protein that in humans is encoded by the ''ZYX'' gene. Function Focal adhesions are actin-rich structures that enable cells to adhere to the extracellular matrix and at which protein complexes involved in signal transduction assemble. Zyxin is a zinc-binding phosphoprotein that concentrates at focal adhesions and along the actin cytoskeleton. Zyxin has an N-terminal proline-rich domain and three LIM domain LIM domains are protein structural domains, composed of two contiguous zinc fingers, separated by a two-amino acid residue hydrophobic linker.

Protein Kinase N1
Serine/threonine-protein kinase N1 is an enzyme that in humans is encoded by the ''PKN1'' gene. Function The protein encoded by this gene belongs to the protein kinase C superfamily. This kinase is activated by Rho family of small G proteins and may mediate the Rho-dependent signaling pathway. This kinase can be activated by phospholipids and by limited proteolysis. The 3-phosphoinositide dependent protein kinase-1 (PDPK1/PDK1) is reported to phosphorylate this kinase, which may mediate insulin signals to the actin cytoskeleton. The proteolytic activation of this kinase by caspase-3 or related proteases during apoptosis suggests its role in signal transduction related to apoptosis. Alternatively spliced transcript variants encoding distinct isoforms have been observed. Interactions Protein kinase N1 has been shown to interact with: * AKAP9, * Actinin, alpha 1, * CCDC85B, * NEFL, * NEUROD2 * Phosphoinositide-dependent kinase-1, * Phospholipase D1, * RHOA, and * ...

Collagen, Type XVII, Alpha 1
Collagen XVII, previously called BP180, is a transmembrane protein which plays a critical role in maintaining the linkage between the intracellular and the extracellular structural elements involved in epidermal adhesion, identified by Diaz and colleagues in 1990. COL17A1 is the official name of the gene. It encodes the alpha chain of type XVII collagen. Collagen XVII is a transmembrane protein, like collagen XIII, XXIII and XXV. Collagen XVII is a structural component of hemidesmosomes, multiprotein complexes at the dermal-epidermal basement membrane zone that mediate adhesion of keratinocytes to the underlying membrane. It also appears to be a key protein in maintaining the integrity of the corneal epithelium. Mutations in this gene are associated with both generalized atrophic benign and junctional epidermolysis bullosa, as well as recurrent corneal erosions, and expression of this gene is abnormal in various cancers. Two homotrimeric forms of type XVII collagen exist. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residue (biochemistry), residues. Proteins perform a vast array of functions within organisms, including Enzyme catalysis, catalysing metabolic reactions, DNA replication, Cell signaling, responding to stimuli, providing Cytoskeleton, structure to cells and Fibrous protein, organisms, and Intracellular transport, transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the Nucleic acid sequence, nucleotide sequence of their genes, and which usually results in protein folding into a specific Protein structure, 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called pep ...

Gene
In biology, the word gene has two meanings. The Mendelian gene is a basic unit of heredity. The molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and non-coding genes. During gene expression (the synthesis of Gene product, RNA or protein from a gene), DNA is first transcription (biology), copied into RNA. RNA can be non-coding RNA, directly functional or be the intermediate protein biosynthesis, template for the synthesis of a protein. The transmission of genes to an organism's offspring, is the basis of the inheritance of phenotypic traits from one generation to the next. These genes make up different DNA sequences, together called a genotype, that is specific to every given individual, within the gene pool of the population (biology), population of a given species. The genotype, along with environmental and developmental factors, ultimately determines the phenotype ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
