MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] RABGEF1 forms a complex with rabaptin-5 (RABPT5; MIM 603616) that is required for endocytic membrane fusion, and it serves as a specific guanine nucleotide exchange factor (GEF) for RAB5 (RAB5A; MIM 179512) (Horiuchi et al., 1997 [PubMed 9323142]).[supplied by OMIM, Mar 2010]
PHENOTYPE: Nullizygous mutations can cause neonatal or postnatal lethality associated with severe skin inflammation, high mast cell numbers and serum levels of IgE and histamine, and enhanced mast cell degranulation and release of mediators and cytokines in response to high affinity IgE receptor aggregation.
