What's a GeneRIF?

Demonstrated the antimicrobial activity of recombinant beta-defensin 22 against E coli and Candida albicans. It has lectin-like ability, binding to heparin beads. This heparin-binding activity implies potential roles in fertilisation capabilities of sperm.
Title: Rat recombinant β-defensin 22 is a heparin-binding protein with antimicrobial activity.

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.
