Protein

Inactive glycosyltransferase 25 family member 3

Gene

CERCAM

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Probable cell adhesion protein involved in leukocyte transmigration across the blood-brain barrier. Does not express any beta-galactosyltransferase activity in vitro.2 Publications

Caution

Has no glucosyltransferase activity. Concerning beta-galactosyltransferase activity, the level of CERCAM could be too low to detect any activity when tested in transfected insect cells.Curated
