Semaphorin-4D (SEMA4D) also known as Cluster of Differentiation 100 (CD100), is a protein of the semaphorin family that in humans is encoded by the SEMA4D gene. [5]
Semaphorin 4D (Sema 4D) is an axon guidance molecule which is secreted by oligodendrocytes and induces growth cone collapse in the central nervous system. By binding plexin B1 receptor it functions as an R-Ras GTPase-activating protein (GAP) and repels axon growth cones in both the mature central nervous system. [6]
In the immune system, CD100 binds CD72 to activate B cells and dendritic cells, though much about this interaction is still under investigation. [7] [8]
During skin damage repairs, SEMA4D interacts with Plexin B2 on Gamma delta T cells to play a role in the healing process. [9]
Complement receptor type 2 (CR2), also known as complement C3d receptor, Epstein-Barr virus receptor, and CD21, is a protein that in humans is encoded by the CR2 gene.
Chemokine ligand 20 (CCL20) or liver activation regulated chemokine (LARC) or Macrophage Inflammatory Protein-3 (MIP3A) is a small cytokine belonging to the CC chemokine family. It is strongly chemotactic for lymphocytes and weakly attracts neutrophils. CCL20 is implicated in the formation and function of mucosal lymphoid tissues via chemoattraction of lymphocytes and dendritic cells towards the epithelial cells surrounding these tissues. CCL20 elicits its effects on its target cells by binding and activating the chemokine receptor CCR6.
Chemokine receptor 6 also known as CCR6 is a CC chemokine receptor protein which in humans is encoded by the CCR6 gene. CCR6 has also recently been designated CD196. The gene is located on the long arm of Chromosome 6 (6q27) on the Watson (plus) strand. It is 139,737 bases long and encodes a protein of 374 amino acids.
Chemokine-binding protein 2 is a protein that in humans is encoded by the CCBP2 gene.
Signal regulatory protein α (SIRPα) is a regulatory membrane glycoprotein from SIRP family expressed mainly by myeloid cells and also by stem cells or neurons.
CD48 antigen also known as B-lymphocyte activation marker (BLAST-1) or signaling lymphocytic activation molecule 2 (SLAMF2) is a protein that in humans is encoded by the CD48 gene.
Plexin B1 is a protein of the plexin family that in humans is encoded by the PLXNB1 gene.
NKG2-F type II integral membrane protein is a protein that in humans is encoded by the KLRC4 gene.
Killer cell immunoglobulin-like receptor 3DL2 is a protein that in humans is encoded by the KIR3DL2 gene.
SLAM family member 6 is a protein that in humans is encoded by the SLAMF6 gene.
Rnd1 is a small signaling G protein, and is a member of the Rnd subgroup of the Rho family of GTPases. It is encoded by the gene RND1.
Transcription factor 7 is the gene that in humans encodes for the TCF1 protein.
CD6 is a human protein encoded by the CD6 gene.
Interleukin 21 receptor is a type I cytokine receptor. IL21R is its human gene.
Natural cytotoxicity triggering receptor 2 is a protein that in humans is encoded by the NCR2 gene. NCR2 has also been designated as CD336, NKp44, NKP44; NK-p44, LY95, and dJ149M18.1.
RAS guanyl-releasing protein 1 is a protein that in humans is encoded by the RASGRP1 gene.
Semaphorin-4A is a protein that in humans is encoded by the SEMA4A gene.
Leukocyte immunoglobulin-like receptor subfamily A member 2 is a protein that in humans is encoded by the LILRA2 gene.
CD160 antigen is a protein that in humans is encoded by the CD160 gene.
NLRC5, short for NOD-like receptor family CARD domain containing 5, is an intracellular protein that plays a role in the immune system. NLRC5 is a pattern recognition receptor implicated in innate immunity to viruses potentially by regulating interferon activity.
