What's a GeneRIF?

study reports on the cellular function of BPIFB6 in the regulation of secretory pathway trafficking and Golgi complex morphology; in addition, findings show that BPIFB6 functions as a positive regulator of enterovirus replication via its regulation of the secretory pathway

Title: New genetic associations detected in a host response study to hepatitis B vaccine.
BPIL3 maps to Chromosome 20q11; thus, these novel genes form a cluster with BPI and two other members of the LT/LBP gene family on the long arm of human Chr 20. AA sequence is reported.
Title: Three new human members of the lipid transfer/lipopolysaccharide binding protein family (LT/LBP).

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.
