The function of JKAMP (JNK1/MAPK8 associated membrane protein, Ensembl gene identifier ENSG00000050130) is as follows. Regulates the duration of MAPK8 activity in response to various stress stimuli (By similarity). Facilitates degradation of misfolded endoplasmic reticulum (ER) proteins through the recruitment of components of the proteasome and endoplasmic reticulum-associated degradation (ERAD) system (PubMed:18784250). .
