RING finger protein 4 is a protein that in humans is encoded by the RNF4 gene. [5] [6]
The protein encoded by this gene contains a RING finger domain and acts as a transcription factor. This protein has been shown to interact with, and inhibit the activity of, TRPS1, a transcription suppressor of GATA-mediated transcription. Transcription repressor ZNF278/PATZ1 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. [6]
RNF4 has been shown to interact with TCF20, [7] PATZ1 [8] [9] and Androgen receptor. [9] [10] [11] RNF4 has been shown to be responsible for the degradation of the Werner syndrome helicase in MSI-H cells after WRN inhibition. [12]
