Summary: Enables several functions, including chromatin binding activity; mRNA 3'-UTR binding activity; and ribonucleoprotein complex binding activity. Involved in positive regulation of cold-induced thermogenesis. Acts upstream of or within germ cell development and post-transcriptional regulation of gene expression. Located in cytoplasm. Part of ribonucleoprotein complex. Is expressed in several structures, including eye; gonad; lung; trunk somite; and uterus. Orthologous to human YBX2 (Y-box binding protein 2).

mRNAs, possibly in a complex with MSY2 and PADI6, are bound in the cytoplasmic lattices (CPLs) and may play a role in securing the mRNA-MSY2 complex to the CPLs.
Title: Role for PADI6 in securing the mRNA-MSY2 complex to the oocyte cytoplasmic lattices.
YBX2 has the important role of coordinating the storage of translationally repressed mRNAs in round spermatids by inhibiting translational activity and the degradation of transcripts via translation-dependent deadenylation.
Title: Position-dependent interactions of Y-box protein 2 (YBX2) with mRNA enable mRNA storage in round spermatids by repressing mRNA translation and blocking translation-dependent mRNA decay.
homozygous double mutants could not be generated as haploinsufficiency of both Ybx2 and Ybx3 caused sterility characterized by extensive defects in spermatid differentiation.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
