Probable transcription factor; required for proper organization of muscle myofilaments and for their recruitment to the M line. Expressed in body wall muscle and gonad (at protein level). Expressed from early embryogenesis and throughout all developmental stages (at protein level) (PubMed:22616817). Expressed in body wall muscle in embryos, young larvae and adults (at protein level) (PubMed:22616817). RNAi-mediated knockdown causes paralysis and arrested elongation at the two-fold stage of embryonic development. Belongs to the krueppel C2H2-type zinc-finger protein family.
