REPS1 (RALBP1-associated Eps domain-containing protein 1) is a multidomain adaptor protein encoded by the REPS1 gene in humans. It is primarily involved in intracellular signaling and membrane trafficking processes. Structurally, REPS1 contains EH (Eps15 homology) and PB1 (Phox and Bem1) domains, which facilitate protein-protein interactions, enabling its role as a scaffold to recruit downstream effectors. It binds directly to RalBP1 (Ral-binding protein 1), a key effector of the small GTPase Ral, linking Ral signaling to endocytic regulation.
REPS1 is implicated in clathrin-mediated endocytosis, vesicle transport, and receptor tyrosine kinase signaling, particularly EGFR (epidermal growth factor receptor) pathways. Studies suggest its involvement in modulating cell proliferation, migration, and apoptosis. Dysregulation of REPS1 has been associated with pathological conditions, including cancer. For instance, REPS1 overexpression is observed in colorectal cancer and glioblastoma, where it may promote tumor growth and metastasis by enhancing oncogenic signaling or suppressing apoptosis. Conversely, its reduced expression in some contexts correlates with chemoresistance.
Recent research highlights REPS1's potential role in neurological disorders, though mechanisms remain unclear. Its interaction with synaptic proteins hints at involvement in neuronal signaling or synaptic plasticity. Despite progress, REPS1's full functional scope and therapeutic relevance require further exploration, particularly in tissue-specific regulation and cross-talk with other signaling networks.
