basic FUNCTION
| catalyzing tyrosine o-sulfation of proteins |
|
acting in targeting and retention of the enzyme to the trans-Golgi compartment |
|
transfer the sulfate moiety to proteins predominantly designated for secretion |
|
may be functional as homodimer/oligomer in the trans-Golgi compartment |
|
involved in photoreceptor outer segment morphogenesis, retinal function and retinal anatomy |
|
tyrosine O-sulfation is a post-translational modification catalyzed by two tyrosylprotein sulfotransferases (TPST1 and TPST2) in the trans-Golgi network |
