Enables RNA polymerase II transcription regulatory region sequence-specific DNA binding activity and carboxypeptidase activity. Acts upstream of or within regulation of transcription, DNA-templated. Located in extracellular space. Is expressed in several structures, including alimentary system; cardiovascular system; genitourinary system; nervous system; and skeleton. Human ortholog(s) of this gene implicated in Ehlers-Danlos syndrome classic-like 2. Orthologous to human AEBP1 (AE binding protein 1). [provided by Alliance of Genome Resources, Apr 2022]
