Functional Description ? help Back to Top
Source	Description
UniProt	Transcription activator that acts as a positive regulator of male germline development by promoting both gametic cell specification and cell cycle progression (PubMed:15694308, PubMed:15618418, PubMed:19300502, PubMed:21285328). Binds to canonical MYB sites 5'-AACCGTC-3', 5'-AAACCGC-3' and 5'-AACCGT-3' in promoters to trigger the expression of male germline-specific or enriched genes (e.g. MGH3, GEX2 and GCS1), including those required for fertilization (PubMed:21285328, PubMed:19300502). Required for sperm cell specification leading to pollen maturation by activating a germline-specific regulon (PubMed:21285328, PubMed:15694308, PubMed:15618418, PubMed:19300502). Involved in pollen mitosis entry at G2-M transition via the regulation of CYCB1-1, DAZ1 and DAZ2 expression (PubMed:15618418, PubMed:19300502, PubMed:24876252). {ECO:0000269\|PubMed:15618418, ECO:0000269\|PubMed:15694308, ECO:0000269\|PubMed:19300502, ECO:0000269\|PubMed:21285328, ECO:0000269\|PubMed:24876252}.

Regulation -- Description ? help Back to Top
Source	Description
UniProt	INDUCTION: Repressed by the microRNA 159 (miR159); the production of miR159 is stimulated by the anaphase promoting complex/cyclosome (APC/C) (PubMed:21441434). Activated by ARID1 in male germline cells via specific histone acetylation regulation (e.g. H3K9Ac) (PubMed:25057814). {ECO:0000269\|PubMed:21441434, ECO:0000269\|PubMed:25057814}.
