Ontology
molecular_function
Synonyms
T cell receptor activity, alpha-beta T cell receptor activity, gamma-delta T cell receptor activity
Alternate IDs

Definition
Combining with an MHC class Ib protein complex and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity. Class Ib here refers to non-classical class I molecules, such as those of the CD1 or HLA-E gene families. Source: GOC:signaling, ISBN:0781735149, GOC:add
