GeneRIFs: Gene References Into Functions

What's a GeneRIF?
  1. SP2 is a major nutrient storage protein from hemolymph for amino acid storage and utilization. Crosstalk between lysine acetylation and ubiquitination of SP2 might imply an important role of lysine acetylation for nutrient storage and utilization in silkworm.
    Title: Lysine acetylation stabilizes SP2 protein in the silkworm Bombyx mori.
  2. These studies revealed that SP2 and SP3 exist in the silkworm body as a heterohexamer formed by one SP2 trimer and one SP3 trimer.
    Title: Crystallographic identification of an unexpected protein complex in silkworm haemolymph.
  3. cDNA encoding an antiviral protein SP-2 against BmNPV was cloned from the midgut of Chinese wild silkworm

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.
