Gene : RIC4 A. thaliana

DB identifier  ? AT5G16490 Secondary Identifier  ? locus:2171332
Name  ? ROP-interactive CRIB motif-containing protein 4 Brief Description  ROP-interactive CRIB motif-containing protein 4
TAIR Computational Description  ROP-interactive CRIB motif-containing protein 4;(source:Araport11)
TAIR Curator Summary  encodes a member of a novel protein family that contains contain a CRIB (for Cdc42/Rac-interactive binding) motif required for their specific interaction with GTP-bound Rop1 (plant-specific Rho GTPase). It interacts with Rop1 and is involved in pollen tube growth and function, and exocytosis in the pollen tube tip. Protein most similar to RIC2 (family subgroup V). Gene is expressed in all tissues examined.Interacts with ROP2 during pavement cell morphogenesis and with ROP1 to promote apical F-actin assembly.

RIC4_ARATH function Functions as a downstream effector of Rho-related GTP binding proteins of the 'Rho of Plants' (ROPs) family. Participates in the propagation of ROP GTPase signals in specific cellular responses. Required for actin cortical microfilament assembly. Activated by ARAC4/ROP2 to promote the assembly of cortical actin microfilaments required for lobe formation and lateral expansion of pavement cells. Interaction with, and activation by ARAC4/ROP2 is inhibited by RIC1. Functions as a downstream effector of ARAC11/ROP1 to promote the assembly of apical F-actin associated with vesicle accumulation in the tip of the growing pollen tube. Counteracts the ARAC11/ROP1-RIC3 pathway, which activates calcium signaling that leads to apical F-actin disassembly associated with exocytosis, to control actin dynamics and pollen tube apical growth. Downstream of ARAC11/ROP1, is involved in the growth responses to the root-colonizing endophytic fungus P.indica.
RIC4_ARATH tissue specificity Expressed in roots, leaves, stems, flowers, siliques and pollen.
