The function of UBE2Q1 (ubiquitin conjugating enzyme E2 Q1, Ensembl gene identifier ENSG00000160714) is as follows. Catalyzes the covalent attachment of ubiquitin to other proteins (PubMed:22496338). May be involved in hormonal homeostasis in females. Involved in regulation of B4GALT1 cell surface expression, B4GALT1-mediated cell adhesion to laminin and embryoid body formation (By similarity). {ECO:0000250|UniProtKB:Q7TSS2, ECO:0000269|PubMed:22496338}.
