Anti-SERP1 Antibody

Stress-associated endoplasmic reticulum (ER) protein 1 (SERP1), also known as ribosome- associated membrane protein 4 (RAMP4), is a Sec61-associated polypeptide that is induced by ER stress [PMID:16705175]. SERP1 interacts with target proteins during their translocation into the lumen of the endoplasmic reticulum. It controls glycosylation of major histocompatibility complex class II-associated invariant chains by a translocational pausing mechanism, and its overexpression stabilizes newly synthesized membrane proteins under ER stress by associating with the Sec61 complex [PMID:10601334]. It is suggested SERP1 is involved in the biosynthesis/processing of secretory proteins
