ARID4B | AT-rich interactive domain-containing protein 4B; Acts as a transcriptional repressor. May function in the assembly and/or enzymatic activity of the Sin3A corepressor complex or in mediating interactions between the complex and other regulatory complexes. Plays a role in the regulation of epigenetic modifications at the PWS/AS imprinting center near the SNRPN promoter, where it might function as part of a complex with RB1 and ARID4A. Involved in spermatogenesis, together with ARID4A, where it functions as a transcriptional coactivator for AR (androgen receptor) and enhances expression [...] (1312 aa) | ||||
ZBTB49 | Zinc finger and BTB domain-containing protein 49; Transcription factor. Inhibits cell proliferation by activating either CDKN1A/p21 transcription or RB1 transcription. [Isoform 3]: Activates RB1 transcription most probably by antagonizing ZBTB17 repression of RB1. Does not bind directly RB1 promoter; Belongs to the krueppel C2H2-type zinc-finger protein family.
