Summary
Enables several functions, including POZ domain binding activity; chromatin insulator sequence binding activity; and protein homodimerization activity. Involved in several processes, including chromatin looping; nuclear axial expansion; and regulation of gene expression. Located in chromosome; microtubule cytoskeleton; and nucleoplasm. Is expressed in several structures, including adult head; central brain primordium; ganglia; and ventral nerve cord primordium. [provided by Alliance of Genome Resources, Jul 2025]
