The protein encoded by the TPST2 gene catalyzes the O-sulfation of tyrosine residues within acidic regions of proteins. The encoded protein is a type II integral membrane protein found in the Golgi body. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq]. Transcript Variant: This variant (1) represents the longer transcript. Variants 1 and 2 both encode the same protein.
