Trim28 | Transcription intermediary factor 1-beta; Nuclear corepressor for KRAB domain-containing zinc finger proteins (KRAB-ZFPs). Mediates gene silencing by recruiting CHD3, a subunit of the nucleosome remodeling and deacetylation (NuRD) complex, and SETDB1 (which specifically methylates histone H3 at 'Lys-9' (H3K9me)) to the promoter regions of KRAB target genes. Enhances transcriptional repression by coordinating the increase in H3K9me, the decrease in histone H3 'Lys-9 and 'Lys-14' acetylation (H3K9ac and H3K14ac, respectively) and the disposition of HP1 proteins to silence gene expression [...] (834 aa) | ||||
Spz1 | Spermatogenic leucine zipper protein 1; Transcription factor that binds to the DNA sequence 5'- CANNTG-3'(E box) and the G-box motif. Directly binds to a guanine-rich region of the PCNA promoter and up-regulates its expression which in turn induces cell transformation and tumor formation. May play an important role in the regulation of cell proliferation and differentiation during spermatogenesis. (378 aa) |
