Probable transcriptional regulator involved in developmental processes. May act as a transcriptional repressor (Potential). Interacts (via homeobox domain) with APBB1 (via PID domain 1). Expressed in mesenchymal cells in proximal ureters at 14 dpc, preceding the smooth muscle precursor cells differentiation and the expression of contractile proteins from 15 dpc. Sumoylated. Belongs to the teashirt C2H2-type zinc-finger protein family. Extended N-terminus. Extended N-terminus.
