Summary: Enables mitogen-activated protein kinase binding activity. Involved in negative regulation of osteoblast differentiation; regulation of bone mineralization; and regulation of stress-activated MAPK cascade. Located in late endosome; mitochondrial intermembrane space; and phagophore assembly site. Colocalizes with autophagosome. Is expressed in several structures, including central nervous system; genitourinary system; gut; hemolymphoid system; and liver and biliary system. Orthologous to human NBR1 (NBR1 autophagy cargo receptor). [provided by Alliance of Genome Resources, Jan 2025]

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.

Description

Transcript Variant: This variant (5) lacks an internal exon, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
