Ready-to-use ELISA kits are available for the detection of serine hydroxymethyltransferase 2 (mitochondrial), an alias of the protein, serine hydroxymethyltransferase 2. The official gene symbol is SHMT2. The protein, with a mass of 56 kDa and length of 504 residues, is reported to be cytoplasmic, nuclear and mitochondrial. It is a member of the SHMT family and may be known by other names, including: serine hydroxymethyltransferase 2 (mitochondrial), serine hydroxymethylase, glycine auxotroph A human complement for hamster, epididymis secretory sperm binding protein Li 51e, GLY A+, and serine hydroxymethyltransferase mitochondrial, and GLYA.
