CC -!- FUNCTION: Chromatin reader that specifically recognizes and binds
CC histone H3 both trimethylated at 'Lys-4' and asymmetrically
CC dimethylated at 'Arg-8' (H3K4me3 and H3R8me2a) and acts as an activator
CC of Wnt signaling pathway downstream of PRMT2. In case of cancer,
CC promotes cell cancer proliferation via activation of the Wnt signaling
CC pathway. Overexpression induces metaphase arrest and chromosomal
CC instability. Localizes to active rDNA loci and promotes the expression
CC of rRNA genes. May play a role in cell-cycle regulation during the
CC transition from gamete to embryo. Involved in oocyte meiotic
CC resumption, a process that takes place before ovulation to resume
CC meiosis of oocytes blocked in prophase I: may act by regulating
CC maternal transcripts to control meiotic resumption.
CC {ECO:0000250|UniProtKB:Q9Y657}.
CC -!- SUBUNIT: Homodimer; may form higher-order oligomers. Interacts with
CC TCF7L2/TCF4; the interaction is direct. Interacts with HABP4 and
CC SERBP1. Interacts with C11orf84/SPINDOC. {ECO:0000250|UniProtKB:Q61142,
CC ECO:0000250|UniProtKB:Q9Y657}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q9Y657}. Nucleus,
CC nucleolus {ECO:0000250|UniProtKB:Q9Y657}.
CC -!- DOMAIN: The 3 tudor-like domains (also named Spin/Ssty repeats)
CC specifically recognize and bind methylated histones. H3K4me3 and
CC H3R8me2a are recognized by tudor-like domains 2 and 1, respectively.
CC {ECO:0000250|UniProtKB:Q9Y657}.
CC -!- PTM: Phosphorylated during oocyte meiotic maturation.
CC {ECO:0000250|UniProtKB:Q61142}.
CC -!- SIMILARITY: Belongs to the SPIN/STSY family. {ECO:0000305}.
