HSPA2 Full-Length MS Protein Standard (NP_068814), Labeled with [U- 13C6, 15N4]-L-Arginine and [U- 13C6, 15N2]-L-Lysine, was produced in human 293 cells (HEK293) with fully chemically defined cell culture medium to obtain incorporation efficiency at Creative-Proteomics. Interacts with ZNF541. Component of the CatSper complex (By similarity). Interacts with RABL2/RABL2A; binds preferentially to GTP-bound RABL2 (By similarity). Interacts with FKBP6.
