BPIFB5P
BPI fold containing family B, member 5 is a non-human protein encoded by the ''Bpifb5'' gene, also known as ''Lplunc5.'' The BPIFB5 protein and ''Bpifb5'' gene have been characterized in mammals such as rodents (mouse, rat) and even-toed ungulates (pig, cow) but are apparently lacking in primates and other vertebrates such as birds, reptiles, and amphibians. The protein in rodents is expressed at moderately high levels in Mucous membrane, mucosa of the airways (respiratory and olfactory epithelium) and at moderate levels in salivary glands, esophagus, and gonads (ovary, testis); in even-toed ungulates expression is high in testis, moderate in brain and striated muscle, and low in kidney. In humans no protein is expressed and it is present only as a pseudogene ''BPIFB5P''. The pseudogene was named based on its functional ortholog found in the other species. Superfamily BPIFB5 is a member of the BPI fold protein superfamily defined by the presence of the bactericidal/permeabil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BPIFA4P
BPI fold containing family A, member 4 (BPIFA4) is a non-human protein encoded by the ''Bpifa4'' gene in monkey and cow. It is also known as Latherin in horse, encoded by the ''Lath/Bpifa4'' gene but somewhat divergent from the other species. Latherin/BPIFA4 is a secreted protein found in saliva and sweat. In humans, no protein is normally expressed and BPIFB5P is present only as a pseudogene ''BPIFB5P''. However, it has appeared as a secreted product in breast cancer cell lines, previously named BASE (''b''reast cancer ''a''nd ''s''alivary gland ''e''xpression) protein. Superfamily BPIFA3 is a member of a BPI fold protein superfamily defined by the presence of the bactericidal/permeability-increasing protein fold (BPI fold) which is formed by two similar domains in a "boomerang" shape. This superfamily is also known as the BPI/LBP/PLUNC family or the BPI/ LPB/ CETP family. The BPI fold creates apolar binding pockets that can interact with hydrophobic and amphipathic mole ...

BPIFB1
BPI fold containing family B, member 1 (BPIFB1) is a protein that in humans is encoded by the ''BPIFB1'' gene.

Lipopolysaccharide
Lipopolysaccharides (LPS) are large molecules consisting of a lipid and a polysaccharide that are bacterial toxins. They are composed of an O-antigen, an outer core, and an inner core all joined by a covalent bond, and are found in the outer membrane of Gram-negative bacteria. Today, the term ''endotoxin'' is often used synonymously with LPS, although there are a few endotoxins (in the original sense of toxins that are inside the bacterial cell that are released when the cell disintegrates) that are not related to LPS, such as the so-called delta endotoxin proteins produced by '' Bacillus thuringiensis''. Lipopolysaccharides can have substantial impacts on human health, primarily through interactions with the immune system. LPS is a potent activator of the immune system and pyrogen (agent that causes fever). In severe cases, LPS can play a role in causing septic shock. In lower levels and over a longer time period, there is evidence LPS may play an important and harmful role ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BPIFB4
BPI fold containing family B, member 4 is a protein that in humans is encoded by the BPIFB4 gene. The study of many populations of centenarians made it possible to identify the longevity-associated variant (LAV) of the BPIFB4 gene. The gene transfer induced forced expression of LAV-BPIFB4 both in old mice and in animal model of hypertension reduced blood pressure and rescued age-related endothelial dysfunction stimulating endothelial nitric oxide synthase activation. As a gene associated with exceptional longevity, capable to protect from hypertension, atherosclerosis, diabetic cardiopathy, frailty, and inflammaging Inflammaging (also known as inflamm-aging or inflamm-ageing) is a chronic, sterile low-grade inflammation that develops with advanced age, in the absence of overt infection, and may contribute to clinical manifestations of other age-related patho ..., LAV-BPIFB4 gene is a promising candidate new ‘drug’ to treat atherosclerosis, its cardiovascular complications ...

BPIFA3
BPI fold containing family A, member 3 is a protein that in humans is encoded by the ''BPIFA3'' gene. The gene is also known as ''SPLUNC3 and C20orf71'' in humans and the orthologous gene in mice is ''1700058C13Rik''. Model organisms Model organisms have been used in the study of BPIFA3 function. A conditional knockout mouse line, called ''1700058C13Riktm1a(KOMP)Wtsi'' was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists — at the Wellcome Trust Sanger Institute. Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion. Twenty three tests were carried out on mutant In biology, and especially in genetics, a mutant is an organism or a new genetic character arising or resulting from an instance of mutation, which is generally an alteration of the DNA sequence of the genome or chromosom ...

Chromosome 20
Chromosome 20 is one of the 23 pairs of chromosomes in humans. Chromosome 20 spans around 66 million base pairs (the building material of DNA) and represents between 2 and 2.5 percent of the total DNA in cells. Chromosome 20 was fully sequenced in 2001 and was reported to contain over 59 million base pairs. Since then, due to sequencing improvements and fixes, the length of chromosome 20 has been updated to just over 66 million base pairs. Genes Number of genes The following are some of the gene count estimates of human chromosome 20. Because researchers use different approaches to genome annotation their predictions of the number of genes on each chromosome varies (for technical details, see gene prediction). Among various projects, the collaborative consensus coding sequence project ( CCDS) takes an extremely conservative strategy. So CCDS's gene number prediction represents a lower bound on the total number of human protein-coding genes. Gene list The following is a ...

Structural Motif
In a polymer, chain-like biological molecule, such as a protein or nucleic acid, a structural motif is a common Biomolecular structure#Tertiary structure, three-dimensional structure that appears in a variety of different, evolutionarily unrelated molecules. A structural motif does not have to be associated with a sequence motif; it can be represented by different and completely unrelated sequences in different proteins or RNA. In nucleic acids Depending upon the sequence and other conditions, nucleic acids can form a variety of structural motifs which is thought to have biological significance. ;Stem-loop: Stem-loop intramolecular base pairing is a pattern that can occur in single-stranded DNA or, more commonly, in RNA. The structure is also known as a hairpin or hairpin loop. It occurs when two regions of the same strand, usually complementary in nucleotide sequence when read in opposite directions, base-pair to form a double helix that ends in an unpaired loop.
