| Protein Name :
Tubby-related protein 1
UniProtKB / Swiss-Prot ID : TULP1_HUMAN
Gene Name (Synonyms) :
Species : Homo sapiens (Human).
Subcellular Localization : Cytoplasm. Cell membrane; Peripheral membrane protein; Cytoplasmic side. Secreted (By similarity). Cell junction, synapse (By similarity). Note=Detected at synapses between photoreceptor cells and second-order neurons. Does not have a cleavable signal pe
Protein Function : Required for normal development of photoreceptor synapses. Required for normal photoreceptor function and for long- term survival of photoreceptor cells. Interacts with cytoskeleton proteins and may play a role in protein transport in photoreceptor cells (By similarity). Binds lipids, especially phosphatidylinositol 3-phosphate, phosphatidylinositol 4- phosphate, phosphatidylinositol 5-phosphate, phosphatidylinositol 3,4-bisphosphate, phosphatidylinositol 4,5-bisphosphate, phosphatidylinositol 3,4,5-bisphosphate, phosphatidylserine and phosphatidic acid (in vitro). Contribute to stimulation of phagocytosis of apoptotic retinal pigment epithelium (RPE) cells and macrophages.
