| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Binds to membranes enriched in phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2). May have a role in transport via clathrin-coated vesicles from the trans-Golgi network to endosomes. Stimulates clathrin assembly. Ref.8 Ref.9 |
| Subunit structure | Binds clathrin heavy chain, GGA2, AP-2 and AP1G1. |
| Subcellular location | Cytoplasm. Cytoplasm › perinuclear region. Membrane; Peripheral membrane protein. Cytoplasmic vesicle › clathrin-coated vesicle. Note: Found throughout the cell, with the exception of the cell surface. Concentrated in the perinuclear region and associated with clathrin-coated vesicles close to the trans-Golgi network. Ref.1 Ref.8 Ref.9 |
| Tissue specificity | Ubiquitously expressed at low to intermediate levels. Ref.8 Ref.9 |
| Polymorphism | Genetic variations in CLINT1 may contribute to susceptibility to schizophrenia and psychotic disorders in some populations. |
| Sequence similarities | Belongs to the epsin family. Contains 1 ENTH (epsin N-terminal homology) domain. |
| Sequence caution | The sequence BAA11488.2 differs from that shown. Reason: Erroneous initiation. |
