Integrin alpha-PS3/beta-PS is a receptor for laminin. Also binds to wb. Important during embryogenesis for the development of the trachea, dorsal vessel and salivary gland, as well as for dorsal closure. Required for short-term memory processes. Minor involvement in the establishment of the oocyte anterior-posterior length. Plays a role in timely border cell migration during oogenesis, probably mediated by JNK signaling. Integrin alpha-PS3/Itgbn is required for effective phagocytosis of apoptotic cells during embryonic development and for the phagocytic elimination of S.aureus by mediating the binding of S.aureus peptidoglycan to larval hemocytes, which probably activates a signaling pathway involving Rac1 and Rac2. Integrin alpha-PS3/Itgbn also regulates Fak activity during neuromuscular junction (NMJ) growth and is required for its activation in presynapsis of NMJs. Seems to be dispensable for major morphogenetic processes.

Belongs to the integrin alpha chain family.
