Previous GeneCards Identifiers for RNF4 Gene
The protein encoded by this gene contains a RING finger motif and acts as a transcription regulator. This protein has been shown to interact with, and inhibit the activity of, TRPS1, a transcription suppressor of GATA-mediated transcription. Transcription repressor ZNF278/PATZ is found to interact with this protein, and thus reduce the enhancement of androgen receptor-dependent transcription mediated by this protein. Studies of the mouse and rat counterparts suggested a role of this protein in spermatogenesis. A pseudogene of this gene is found on chromosome 1.[provided by RefSeq, Jul 2010]
GeneCards Summary for RNF4 Gene
RNF4 (Ring Finger Protein 4) is a Protein Coding gene. Among its related pathways are DNA Double-Strand Break Repair and Class I MHC mediated antigen processing and presentation. GO annotations related to this gene include transcription factor activity, sequence-specific DNA binding and ligase activity.
UniProtKB/Swiss-Prot for RNF4 Gene
E3 ubiquitin-protein ligase which binds polysumoylated chains covalently attached to proteins and mediates Lys-6-, Lys-11-, Lys-48- and Lys-63-linked polyubiquitination of those substrates and their subsequent targeting to the proteasome for degradation. Regulates the degradation of several proteins including PML and the transcriptional activator PEA3. Involved in chromosome alignment and spindle assembly, it regulates the kinetochore CENPH-CENPI-CENPK complex by targeting polysumoylated CENPI to proteasomal degradation. Regulates the cellular responses to hypoxia and heat shock through degradation of respectively EPAS1 and PARP1. Alternatively, it may also bind DNA/nucleosomes and have a more direct role in the regulation of transcription for instance enhancing basal transcription and steroid receptor-mediated transcriptional activation.
