ZNF354A, also called EZNF, KID-1 or TCF17, belongs to the Krueppel C2H2-type zinc-finger family of proteins that contain KRAB domains and act as transcriptional regulators. Expressed primarily in adult kidney, ZNF354A functions as a transcriptional repressor that plays a role in late renal development and is suppressed after renal ischemia. The N-terminus of ZNF354A contains the KRAB domain which confers transcriptional repressor activity, while the C-terminus contains multiple C2H2-zinc fingers. ZNF354A is localized to the nucleolus and is thought to specifically influence development of the proximal tubule by shutting off dispensable or inhibitory genes. Reduced ZNF354A expression prevents proper cell differentiation and may, therefore, be implicated in renal carcinoma. ZNF354B (zinc finger protein 354B) is a 612 amino acid nuclear protein that also belongs to the Krueppel C2H2-type zinc-finger family and is thought to play a role in transcriptional regulation events. |
