third Tudor domain found in Tudor domain-containing protein 6 (TDRD6) and similar proteins
TDRD6, also called antigen NY-CO-45 or cancer/testis antigen 41.2 (CT41.2), is a testis-specific expressed protein that was localized to the chromatoid bodies in germ cells, and is involved in spermiogenesis, chromatoid body formation, and for proper precursor and mature miRNA expression. Mutations in TDRD6 may be associated with human male infertility and early embryonic lethality. TDRD6 contains seven Tudor domains. This model corresponds to the third one. The Tudor domain binds to proteins with dimethylated arginine or lysine residues, and may also bind methylated histone tails to facilitate protein-protein interactions.
Feature 1:putative peptide binding site [polypeptide binding site]
Evidence:
Comment:based on the structures of other Tudor-like family proteins with bound methylated/dimethylated peptides
Comment:In general, the Tudor domain binds to proteins with dimethylated arginine or lysine residues, and may also bind methylated histone tails to facilitate protein-protein interactions.
