Summary: Predicted to enable RNA binding activity and ubiquitin protein ligase activity. Acts upstream of or within chondrocyte hypertrophy; energy homeostasis; and regulation of fat cell differentiation. Predicted to be located in cytoplasm and nucleus. Is expressed in several structures, including central nervous system and genitourinary system. Orthologous to human MEX3C (mex-3 RNA binding family member C).

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.
