CLIP (protein)

CLIP or Class II-associated invariant chain peptide is the part of the invariant chain that binds MHC II groove and remains there until the MHC receptor is fully assembled. The purpose of CLIP is to prevent the binding of an antigen prematurely, which would disrupt the synthesis of MHC II.

Corticotropin-like intermediary peptide
CLIP can also mean corticotropin-like intermediary lobe peptide, which is similar to ACTH.
