Summary: Enables protein heterodimerization activity. Involved in several processes, including behavioral response to ethanol; dorsal trunk growth, open tracheal system; and heart development. Located in apical plasma membrane; basal plasma membrane; and cytoplasm. Part of integrin complex. Is expressed in several structures, including Kenyon cell; epithelium; follicle cell; synaptic neuropil domain; and synaptic neuropil subdomain. Human ortholog(s) of this gene implicated in several diseases, including artery disease (multiple); blood platelet disease (multiple); diabetes mellitus (multiple); retinal vascular disease (multiple); and von Willebrand's disease (multiple). Orthologous to several human genes including ITGA9 (integrin subunit alpha 9). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

the integrin heterodimer alphaPS3/betaPS becomes apically enriched and is required for engulfment by the epithelial follicle cells of the Drosophila ovary.
Title: Polarization of the epithelial layer and apical localization of integrins are required for engulfment of apoptotic cells in the Drosophila ovary.
Study presents evidence that alphaPS2 and alphaPS3 integrin have different and specific functions in the development of retinal glia
Title: Drosophila PS2 and PS3 integrins play distinct roles in retinal photoreceptors-glia interactions.
that integrin alphaPS3/betanu serves as a receptor in the phagocytosis of apoptotic cells and bacteria by Drosophila phagocytes.
Title: Integrin αPS3/βν-mediated phagocytosis of apoptotic cells and bacteria in Drosophila.
We identify a role for the alphaPS3, betaPS1 Integrin dimer in both the early establishment of the apical, pre-luminal domain, as well as a requirement upon Robo for maintained apicalisation of proteins required for lumen formation.
Title: Integrins are required for cardioblast polarisation in Drosophila.
