TMCO1 Full-Length MS Protein Standard (NP_061899), 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. This locus encodes a transmembrane protein. Mutations at this locus have been associated with craniofacial dysmorphism, skeletal anomalies, and mental retardation. Mutations at this locus have also been associated with open angle glaucoma blindness. Alternatively spliced transcript variants have been described.
