CC -!- FUNCTION: Plays an important role in meiotic recombination. Stimulates
CC DMC1-mediated strand exchange required for pairing homologous
CC chromosomes during meiosis. The complex PSMC3IP/MND1 binds DNA,
CC stimulates the recombinase activity of DMC1 as well as DMC1 D-loop
CC formation from double-strand DNA. This complex stabilizes presynaptic
CC RAD51 and DMC1 filaments formed on single strand DNA to capture double-
CC strand DNA. This complex stimulates both synaptic and presynaptic
CC critical steps in RAD51 and DMC1-promoted homologous pairing. May
CC inhibit HIV-1 viral protein TAT activity and modulate the activity of
CC proteasomes through association with PSMC3. Acts as a tissue specific
CC coactivator of hormone-dependent transcription mediated by nuclear
CC receptors. {ECO:0000269|PubMed:10806355, ECO:0000269|PubMed:16407260,
CC ECO:0000269|PubMed:21963259}.
CC -!- SUBUNIT: Interacts with the DNA-binding domain of the nuclear receptors
CC NR3C1/GR, ESR2/ER-beta, THRB and RXRA (By similarity). Forms a stable
CC heterodimer with MND1. Interacts with PSMC3/TBP1. {ECO:0000250,
CC ECO:0000269|PubMed:10806355, ECO:0000269|PubMed:16407260}.
CC -!- INTERACTION:
CC Q9P2W1; Q9BWT6: MND1; NbExp=5; IntAct=EBI-9057595, EBI-11137441;
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:11739747}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=3;
CC Name=1;
CC IsoId=Q9P2W1-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q9P2W1-2; Sequence=VSP_030213;
CC Name=3;
CC IsoId=Q9P2W1-3; Sequence=VSP_047716;
CC -!- TISSUE SPECIFICITY: Highly expressed in testis and colon.
CC {ECO:0000269|PubMed:11739747, ECO:0000269|PubMed:7490091}.
CC -!- INDUCTION: Overexpressed in leiomyomas compared to myometrium.
CC {ECO:0000269|PubMed:17716379}.
CC -!- PTM: PTM: Phosphorylated by PKA, PKC and MAPK. {ECO:0000250}.
CC -!- DISEASE: Ovarian dysgenesis 3 (ODG3) [MIM:614324]: A disorder
CC characterized by lack of spontaneous pubertal development, primary
CC amenorrhea, uterine hypoplasia, and hypergonadotropic hypogonadism as a
CC result of streak gonads. {ECO:0000269|PubMed:21963259}. Note=The
CC disease is caused by variants affecting the gene represented in this
CC entry.
CC -!- SIMILARITY: Belongs to the HOP2 family. {ECO:0000305}.
