PVRL1
Poliovirus receptor-related 1 (PVRL1), also known as nectin-1 and CD111 (formerly herpesvirus entry mediator C, HVEC) is a human protein of the immunoglobulin superfamily (IgSF), also considered a member of the nectins. It is a membrane protein with three extracellular immunoglobulin domains, a single transmembrane helix and a cytoplasmic tail. The protein can mediate Ca2+-independent cellular adhesion further characterizing it as IgSF cell adhesion molecule (IgSF CAM). Function PVRL1 is an adhesion molecule found in a wide range of tissues where it localizes in various junctions such as the adherens junction of epithelial tissue or the chemical synapse of neurons. The cytoplasmic tail of PVRL1 can bind the protein afadin which is a scaffolding protein that binds actin. In the chemical synapse PVRL1 interacts with PVRL3 (nectin-3) and both proteins can be found in neuronal tissue already in early stages of brain development as well as in aging brains.

BCR Gene
The breakpoint cluster region protein (BCR) also known as renal carcinoma antigen NY-REN-26 is a protein that in humans is encoded by the ''BCR'' gene. ''BCR'' is one of the two genes in the ''BCR-ABL'' fusion protein, which is associated with the Philadelphia chromosome. Two transcript variants encoding different isoforms have been found for this gene. Function Although the BCR- ABL fusion protein has been much studied, the function of the normal BCR gene product is still not clear. The protein has serine/threonine kinase activity and is a guanine nucleotide exchange factor for the Rho family of GTPases including RhoA. Clinical significance A reciprocal translocation between chromosomes 22 and 9 produces the Philadelphia chromosome, which is often found in patients with chronic myelogenous leukemia. The chromosome 22 breakpoint for this translocation is located within the ''BCR'' gene. The translocation produces a fusion protein that is encoded by sequence from both ''BCR'' ...

EPHB3
Ephrin type-B receptor 3 is a protein that in humans is encoded by the ''EPHB3'' gene. Function Ephrin receptors and their ligands, the ephrins, mediate numerous developmental processes, particularly in the nervous system. Based on their structures and sequence relationships, ephrins are divided into the ephrin-A (EFNA) class, which are anchored to the membrane by a glycosylphosphatidylinositol linkage, and the ephrin-B (EFNB) class, which are transmembrane proteins. The Eph family of receptors are divided into 2 groups based on the similarity of their extracellular domain sequences and their affinities for binding ephrin-A and ephrin-B ligands. Ephrin receptors make up the largest subgroup of the receptor tyrosine kinase (RTK) family. The protein encoded by this gene is a receptor for ephrin-B family members. Interactions EPHB3 has been shown to interact with MLLT4 and RAS p21 protein activator 1 RAS p21 protein activator 1 or RasGAP (Ras GTPase activating protein), also k ...

F11 Receptor
Junctional adhesion molecule A is a protein that in humans is encoded by the ''F11R'' gene. It has also been designated as CD321 (cluster of differentiation 321). Function Tight junctions represent one mode of cell-to-cell adhesion in epithelial or endothelial cell sheets, forming continuous seals around cells and serving as a physical barrier to prevent solutes and water from passing freely through the paracellular space. The protein encoded by this immunoglobulin superfamily gene member is an important regulator of tight junction assembly in epithelia. In addition, the encoded protein can act as (1) a receptor for reovirus, (2) a ligand for the integrin LFA1, involved in leukocyte transmigration, and (3) a platelet receptor. Multiple transcript variants encoding two different isoforms have been found for this gene. Interactions F11 receptor has been shown to interact with MLLT4, CASK and Tight junction protein 1 Zonula occludens-1 ZO-1, also known as Tight junction prote ...

LIM domain only 2 (rhombotin-like 1), also known as LMO2, RBTNL1, RBTN2, RHOM2, LIM Domain Only Protein 2, TTG2, and T-Cell Translocation Protein 2, is a protein which in humans is encoded by the ''LMO2'' gene. Function LMO2 encodes a cysteine-rich, two LIM domain protein that is required for yolk sac erythropoiesis. The LMO2 protein has a central and crucial role in hematopoietic development and is highly conserved. Clinical significance Aberrant ''LMO2'' expression is a significant feature of T cell acute lymphoblastic leukaemia with multiple described mechanisms of activation. The LMO2 transcription start site is located approximately 25 kb downstream from the 11p13 T-cell translocation cluster (11p13 ttc), where a number of T-cell acute lymphoblastic leukemia-specific translocations occur. An upstream noncoding DNA element is also the site of recurrent mutations in T cell acute lymphoblastic leukaemia, leading the recruitment of the transcription factor MYB and signif ...

RAP1A
Ras-related protein Rap-1A is a protein that in humans is encoded by the ''RAP1A'' gene. Function The product of this gene belongs to the family of Ras-related proteins. These proteins share approximately 50% amino acid identity with the classical RAS proteins and have numerous structural features in common. The most striking difference between RAP proteins and RAS proteins resides in their 61st amino acid: glutamine in RAS is replaced by threonine in RAP proteins. The product of this gene counteracts the mitogenic function of RAS because it can interact with RAS GAPs and RAF in a competitive manner. Two transcript variants encoding the same protein have been identified for this gene. Interactions RAP1A has been shown to interact with: * C-Raf, * MLLT4, * PDE6D, * RALGDS, * RAPGEF2, and * TSC2 Tuberous Sclerosis Complex 2 (TSC2), also known as Tuberin, is a protein that in humans is encoded by the ''TSC2'' gene.

Tight Junction Protein 1
Zonula occludens-1 ZO-1, also known as Tight junction protein-1 is a 220-kD peripheral membrane protein that is encoded by the ''TJP1'' gene in humans. It belongs to the family of ''zonula occludens proteins'' (ZO-1, ZO-2, and ZO-3), which are tight junction-associated proteins and of which, ZO-1 is the first to be cloned. It was first isolated in 1986 by Stevenson and Goodenough using a monoclonal antibody raised in rodent liver to recognise a 225-kD polypeptide in whole liver homogenates and in tight junction-enriched membrane fractions. It has a role as a scaffold protein which cross-links and anchors Tight Junction (TJ) strand proteins, which are fibril-like structures within the lipid bilayer, to the actin cytoskeleton. Function This gene encodes a protein located on a cytoplasmic membrane surface of intercellular tight junctions. The encoded protein may be involved in signal transduction at cell–cell junctions.
