What's a GeneRIF?

Deficiency in the endocytic adaptor proteins PHETA1/2 impairs renal and craniofacial development.
Title: Deficiency in the endocytic adaptor proteins PHETA1/2 impairs renal and craniofacial development.
Two novel OCRL1-binding proteins, termed inositol polyphosphate phosphatase interacting protein of 27 kDa (IPIP27)A and B (also known as Ses1 and 2), that also bind the related 5-phosphatase Inpp5b, were identified.
Title: The PH domain proteins IPIP27A and B link OCRL1 to receptor recycling in the endocytic pathway.
Two closely related endocytic proteins, Ses1 and Ses2, which interact with OCRL, were identified. The interaction is mediated by a short amino acid motif similar to that used by the rab-5 effector APPL1.
Title: Two closely related endocytic proteins that share a common OCRL-binding motif with APPL1.

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.
