General annotation (Comments)

Function	Has hydrolase activity towards p-nitrophenyl butyrate (in vitro). May activate transcription. Ref.5
Subunit structure	May interact with TAF1.
Subcellular location	Cytoplasm. Nucleus. Note: Predominantly cytoplasmic. Ref.4 Ref.5
Tissue specificity	Ubiquitous. Detected in spleen, thymus, prostate, testis, ovary, small intestine, colon, peripheral blood leukocyte, heart, placenta, lung, liver, skeletal muscle, pancreas and kidney. Ref.5
Sequence similarities	Belongs to the AB hydrolase superfamily. ABHD14 family.
Sequence caution	The sequence AAH50650.1 differs from that shown. Reason: Erroneous initiation.
