Also known as: CG8573; Dmel\CG8573; su(hw); su(HW); Su(hw); Su(Hw); Su(HW); SU(HW); suHw; SUHW; Su[Hw]
Summary: Enables chromatin insulator sequence binding activity; euchromatin binding activity; and sequence-specific DNA binding activity. Involved in negative regulation of macromolecule biosynthetic process; protein localization to euchromatin; and response to ecdysone. Located in chromatin and nucleus. Is expressed in several structures, including germline cell; gut section; head epidermis primordium; somatic trunk mesoderm derivative; and trunk visceral muscle primordium. Orthologous to human ZNF358 (zinc finger protein 358). [provided by Alliance of Genome Resources, Dec 2024]
