GeneRIFs: Gene References Into Functions

What's a GeneRIF?

GRAMD2a, but not GRAMD1a, co-localizes with the E-Syt2/3 tethers at endoplasmic reticulum-plasma membrane contact sites in a phosphatidylinositol phosphate lipid-dependent manner. Data from an analysis of cells lacking GRAMD2a suggest that it is an organizer of the membrane contact sites with pleiotropic functions including calcium homeostasis.

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.
