Summary: Predicted to enable several functions, including Hsp70 protein binding activity; low-density lipoprotein particle receptor binding activity; and proteasome binding activity. Predicted to be involved in negative regulation of inclusion body assembly. Predicted to be located in mitochondrion and nucleus.

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.
