What's a GeneRIF?

Invasive pulmonary aspergillosis in immunocompromised rats caused a dramatic increase in chitinase activity.
Title: Evidence supporting a role for mammalian chitinases in efficacy of caspofungin against experimental aspergillosis in immunocompromised rats.
Report of cDNA that encodes a protein with a characteristic N-terminal 21 amino acid endoplasmic reticulum signal peptide; the putative protein is highly homologous to acidic mammalian chitinase (AMCase) precursor of mouse and human.

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.
