Summary: This gene encodes a protein that belongs to the FYVE zinc finger family of proteins. The encoded protein interacts with Ras-related proteins that regulate membrane trafficking. A missense mutation in this gene is associated with a defect in the early endocytic pathway. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2014]

RABENOSYN separation-of-function mutations uncouple endosomal recycling from lysosomal degradation, causing a distinct Mendelian disorder.
Title: RABENOSYN separation-of-function mutations uncouple endosomal recycling from lysosomal degradation, causing a distinct Mendelian disorder.
The Rab-binding module of FERARI (factors for endosome recycling and Rab interactions) consists of Rab11FIP5 and rabenosyn-5, while the SNARE-interacting module comprises VPS45 and VIPAS39.
Title: FERARI is required for Rab11-dependent endocytic recycling.
3 consanguineous siblings with syndromic congenital myelofibrosis had a variant (NM_022340.3:c.289G>C; NP_001289307.1:p.Gly97Arg) in RBSN. All 3 were homozygous; the parents and a cousin were heterozygous. RBSN loss of function causes a severe syndromic form of congenital myelofibrosis, confirming that rabenosyn-5 plays a vital role in human development and hematopoiesis.
Title: Syndromic congenital myelofibrosis associated with a loss-of-function variant in RBSN.
A functional defect in the endocytic pathway resulting from a point mutation in Rabenosyn-5 leads to severe multi-organ disorder.
Title: Single point mutation in Rabenosyn-5 in a female with intractable seizures and evidence of defective endocytotic trafficking.
transferrin receptors are delivered selectively from clathrin-coated pits on the plasma membrane into a specific subpopulation of endosomes enriched in the multivalent Rab GTPase and phosphoinositide-binding protein Rabenosyn-5.
Title: Rabenosyn-5 defines the fate of the transferrin receptor following clathrin-mediated endocytosis.
Data implicate hVps45 and Rabenosyn-5 in post early endosome transport, and suggest that their interaction serves as a nexus to promote bidirectional transport along the endosome-to-recycling compartment and endosome-to-Golgi axes.
Title: Common and distinct roles for the binding partners Rabenosyn-5 and Vps45 in the regulation of endocytic trafficking in mammalian cells.
results demonstrate that even the structurally similar effector domains in rabenosyn-5 can achieve highly selective recognition of distinct subsets of Rab GTPases exclusively through interactions with the switch and interswitch regions
Title: Structural basis of family-wide Rab GTPase recognition by rabenosyn-5.

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.

Status: REVIEWED

Description

Transcript Variant: This variant (3) lacks several exons and its 3' terminal exon extends past a splice site that is used in variant 1. This variant is represented as non-coding because it lacks a large portion of the coding region found in variant 1 and the predicted protein does not meet RefSeq quality criteria.
