CBL-B is an E3 ubiquitin-protein ligase that in humans is encoded by the CBLB gene. ^{[5] [6]} CBLB is a member of the CBL gene family.

Function

CBL-B functions as a negative regulator of T-cell activation. ^[7] CBL-B expression in T cells causes ligand-induced T cell receptor down-modulation, controlling the activation degree of T cells during antigen presentation. ^{[8] [9]}

Clinical significance

Mutation of the CBLB gene has been associated with autoimmune conditions such as type 1 diabetes. ^{[10] [11]}

Interactions

CBLB has been shown to interact with:

• CRKL, ^[12]
• Epidermal growth factor receptor, ^{[13] [14]}
• Grb2, ^{[12] [15]}
• NEDD4, ^[16]
• PIK3R1, ^{[12] [15]} and
• SH3KBP1. ^[17]
