Rabbit Anti-RABEP1 antibody
RABEP1 is a Rab effector protein acting as linker between gamma-adaptin, RAB4A and RAB5A. It is involved in endocytic membrane fusion and membrane trafficking of recycling endosomes. Stimulates RABGEF1 mediated nucleotide exchange on RAB5A.
Function:
Rab effector protein acting as linker between gamma-adaptin, RAB4A and RAB5A. Involved in endocytic membrane fusion and membrane trafficking of recycling endosomes. Stimulates RABGEF1 mediated nucleotide exchange on RAB5A.
Subunit:
Homodimer when bound to RAB5A. Heterodimer with RABGEF1. The heterodimer binds RAB4A and RAB5A that have been activated by GTP-binding. Binds TSC2, GGA1, GGA2, GGA3, AP1G1 and AP1G2. Interacts with ECM29.
Subcellular Location:
Cytoplasm. Early endosome. Recycling endosome
Post-translational modifications:
Proteolytic cleavage by caspases in apoptotic cells causes loss of endosome fusion activity.
Similarity:
Belongs to the rabaptin family.
