Peptide Name: PCYT1B (311-321) pS315+pS319
Product Use: Services as a blocking peptide for use with the PCYT1B-pS315+pS319 rabbit polyclonal antibody (Cat. No.: AB-PN546) that is also available from Kinexus. This phosphopeptide may also be useful as a substrate for screening the phosphatase activity of protein phosphatases. The peptide sequence is located near the C-terminus of the protein. This is the main in vivo phosphorylation site in PCYT1B. The effect of its phosphorylation is unclear.

Related Product 1: PCYT1B - pS315+pS319 phosphosite-specific antibody (Cat. No.: AB-PN546) Scientific Background: PCYT1B is the rate limiting enzyme in the biosynthetic pathway for phosphatidylcholine. It catalyzes the reaction: CTP + phosphocholine = diphosphate + CDP-choline. It is an ambiquitous enzyme that resides in the cytoplasm of cells in an inactive form. Diacylglycerol, acidic phospholipids and fatty acids drive the binding of PCYT1B to the endoplasmic reticulum and stimulation of its catalytic activity.
