CD11c, also known as Integrin, alpha X (ITGAX), is a gene that encodes for CD11c.
Integrin, alpha L , also known as ITGAL, is a human gene which functions in the immune system. It is involved in cellular adhesion and costimulatory signaling. It is the target of the drug efalizumab.
Integrin alpha M (ITGAM) is one protein subunit that forms heterodimeric integrin alpha-M beta-2 (αMβ2) molecule, also known as macrophage-1 antigen (Mac-1) or complement receptor 3 (CR3). ITGAM is also known as CR3A, and cluster of differentiation molecule 11B (CD11B). The second chain of αMβ2 is the common integrin β2 subunit known as CD18, and integrin αMβ2 thus belongs to the β2 subfamily integrins.
In molecular biology, CD18 is an integrin beta chain protein that is encoded by the ITGB2 gene in humans. Upon binding with one of a number of alpha chains, CD18 is capable of forming multiple heterodimers, which play significant roles in cellular adhesion and cell surface signaling, as well as important roles in immune responses. CD18 also exists in soluble, ligand binding forms. Deficiencies in CD18 expression can lead to adhesion defects in circulating white blood cells in humans, reducing the immune system's ability to fight off foreign invaders.
Integrin beta-1 (ITGB1), also known as CD29, is a cell surface receptor that in humans is encoded by the ITGB1 gene. This integrin associates with integrin alpha 1 and integrin alpha 2 to form integrin complexes which function as collagen receptors. It also forms dimers with integrin alpha 3 to form integrin receptors for netrin 1 and reelin. These and other integrin beta 1 complexes have been historically known as very late activation (VLA) antigens.
CD49d is an integrin alpha subunit. It makes up half of the α4β1 lymphocyte homing receptor.
Integrin alpha-2 or CD49b is a protein which in humans is encoded by the CD49b gene.
Integrin alpha-3 is a protein that in humans is encoded by the ITGA3 gene.
ITGA3 is an integrin alpha subunit. Together with beta-1 subunit, it makes up half of the α3β1 integrin duplex that plays a role in neural migration and corticogenesis, acted upon by such factors as netrin-1 and reelin.
Integrin beta-3 (β3) or CD61 is a protein that in humans is encoded by the ITGB3 gene. CD61 is a cluster of differentiation found on thrombocytes.
CD9 antigen is a protein that in humans is encoded by the CD9 gene.
Leukocyte surface antigen CD53 is a protein that in humans is encoded by the CD53 gene.
CD63 antigen is a protein that in humans is encoded by the CD63 gene. CD63 is mainly associated with membranes of intracellular vesicles, although cell surface expression may be induced.
CD151 molecule, also known as CD151, is a human gene.
Integrin, alpha E (ITGAE) also known as CD103 is an integrin protein that in human is encoded by the ITGAE gene. CD103 binds integrin beta 7 to form the complete heterodimeric integrin molecule αEβ7, which has no distinct name. The αEβ7 complex is often referred to as "CD103" though this appellation strictly refers only to the αE chain. Note that the β7 subunit can bind with other integrin α chains, such as α4 (CD49d).
Integrin alpha-IIb is a protein that in humans is encoded by the ITGA2B gene. ITGA2B, also known as CD41, encodes integrin alpha chain 2b. Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. Alpha chain 2b undergoes post-translational cleavage to yield disulfide-linked light and heavy chains that join with beta 3 to form a fibrinogen receptor expressed in platelets that plays a crucial role in coagulation. Mutations that interfere with this role result in thrombasthenia. In addition to adhesion, integrins are known to participate in cell-surface mediated signalling.
Integrin alpha-V is a protein that in humans is encoded by the ITGAV gene.
Integrin alpha-5 is a protein that in humans is encoded by the ITGA5 gene.
Integrin alpha-6 is a protein that in humans is encoded by the ITGA6 gene.
Integrin, beta 4 (ITGB4) also known as CD104, is a human gene.
Integrin alpha-D is a protein that in humans is encoded by the ITGAD gene.
