CkIIbeta | Casein kinase II beta subunit (CkIIbeta) encodes the regulatory subunit of the CKII holoenzyme, a protein serine/threonine kinase composed of a and b subunits. Interactions have been reported with other kinases (e.g., the products of PIP4K and S6kII), the RNA-binding protein encoded by orb , the Hedgehog signaling pathway and clock proteins such as the products of tim and per. The product of CkIIbeta functions in oogenesis, neurogenesis, development (brain and other tissues) as well as circadian behavior. (235 aa) | ||||

if | Integrin alpha-PS2 heavy chain; Inflated (if) encodes one of five fly integrin alpha subunits, and when in a heterodimer with an integrin beta subunit makes a receptor for extracellular matrix proteins containing an RGD motif, such as those encoded by Tig, wb laminin and Tsp. It is required in numerous tissues for cell migration and adhesion between cell layers. (1396 aa) | ||||
Rac1 | Ras-related protein Rac1; During various developmental processes, regulates changes in cell morphology in response to extracellular signals. During oogenesis, mediates signaling from the tyrosine kinase (RTK) chemoattractant receptors (Egfr and Pvr) to the guidance pathway that control the directional persistent collective migration of the border cell (BC) cluster through the nurse cells to the oocyte. Once activating by Pvr and Egfr, promotes the formation of forward-directed actin protrusions which stabilize the DE- cadherin (shg)-mediated adhesions.
