ZNF277 is a C2H2-type zinc finger transcription factor with diverse regulatory roles in cellular processes. As a transcriptional regulator, ZNF277 functions as a tumor suppressor gene repressor, specifically inhibiting INK4A/ARF expression and promoting cellular proliferation while suppressing senescence 1. The protein acts as a transit-amplifying cell marker in intestinal homeostasis and functions as an oncogene in colon cancer, where it is regulated by β-catenin signaling 1. Beyond transcriptional control, ZNF277 demonstrates RNA-binding capabilities, acting as a multifunctional RNA-binding protein that regulates thousands of RNA targets and modulates splicing, polyadenylation, stability, and translation 2. The gene shows evolutionary conservation from C. elegans to humans, with expression in early embryonic development suggesting critical roles in differentiation 3. ZNF277 also participates in ribosome assembly through interactions with ribosomal protein uS5, forming part of a conserved regulatory network 4. Clinical relevance includes associations with specific language impairment through microdeletions 5 and involvement in immune responses to mycobacterial infections via circular RNA mechanisms 6. The protein represents a multifaceted regulator integrating transcriptional, post-transcriptional, and ribosomal functions.
