CBLB (gene)
CBL-B is an E3 ubiquitin-protein ligase that in humans is encoded by the CBLB gene.[3][4] CBLB is a member of the CBL gene family.
Function
CBL-B functions as a negative regulator of T-cell activation.[5] CBL-B expression in T cells causes ligand-induced T cell receptor down-modulation, controlling the activation degree of T cells during antigen presentation.[6][7]
Clinical significance
Mutation of the CBLB gene has been associated with autoimmune conditions such as type 1 diabetes.[8][9]
Interactions
CBLB has been shown to interact with:
- CRKL,[10]
- Epidermal growth factor receptor,[11][12]
- Grb2,[10][13]
- NEDD4,[14]
- PIK3R1,[10][13] and
- SH3KBP1.[15]
