The increased expression of the pro-inflammatory and proapoptotic genes, a higher number of apoptotic cells, and increased injury and mortality of the TIM2-deficient mice suggest a protective role of TIM2 in cisplatin-induced nephrotoxicity.

TIM-2 is expressed on B cells and in liver and kidney and is a receptor for H-ferritin endocytosis.

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.
