CBL-B is an E3 ubiquitin-protein ligase that in humans is encoded by the CBLB gene.^[1]^[2] CBLB is a member of the CBL gene family.

Function

CBL-B functions as a negative regulator of T-cell activation.^[3] CBL-B expression in T cells causes ligand-induced T cell receptor down-modulation, controlling the activation degree of T cells during antigen presentation.^[4]^[5]

Clinical significance

Mutation of the CBLB gene has been associated with autoimmune conditions such as type 1 diabetes.^[6]^[7]

Interactions

CBLB has been shown to interact with:

CRKL,^[8]
Epidermal growth factor receptor,^[9]^[10]
Grb2,^[8]^[11]
NEDD4,^[12]
PIK3R1,^[8]^[11] and
SH3KBP1.^[13]
