An Error has occurred retrieving Wikidata item for infobox Putative tyrosine-protein phosphatase auxilin is an enzyme that in humans is encoded by the DNAJC6 gene.[1][2][3]

Function

DNAJC6 belongs to the evolutionarily conserved DNAJ/HSP40 family of proteins, which regulate molecular chaperone activity by stimulating ATPase activity. DNAJ proteins may have up to 3 distinct domains: a conserved 70-amino acid J domain, usually at the N terminus, a glycine/phenylalanine (G/F)-rich region, and a cysteine-rich domain containing 4 motifs resembling a zinc-finger domain (Ohtsuka and Hata, 2000).[3]

Structure

The protein tyrosine phosphatase domain and C2 domain pair of auxilin, located near the N-terminus of the polypeptide, constitute a superdomain, a tandem arrangement of two or more nominally unrelated domains that form a single heritable unit.[4] The phosphatase domain belongs to the auxilin subfamily of lipid phosphatases and is predicted to be catalytically inactive.[5][6]
