Description : (at3g12160 : 299.0) Encodes RABA4D, a member of the Arabidopsis RabA4 subfamily of Rab GTPase proteins. It is transported in exocytic vesicles to the apical tip of pollen tubes where it appears to promote tip growth. Proper localization of RabA4d depends on ROP1, RIC3, and RIC4 activity.; RAB GTPase homolog A4D (RABA4D); FUNCTIONS IN: GTP binding; INVOLVED IN: regulation of pollen tube growth, pollen tube growth, pollen tube development; LOCATED IN: exocytic vesicle, apical part of cell; EXPRESSED IN: 8 plant structures; EXPRESSED DURING: L mature pollen stage, M germinated pollen stage, 4 anthesis, petal differentiation and expansion stage; CONTAINS InterPro DOMAIN/s: Ras GTPase (InterPro:IPR001806), Small GTP-binding protein (InterPro:IPR005225), Small GTPase (InterPro:IPR020851), Ras (InterPro:IPR013753), Ras small GTPase, Rab type (InterPro:IPR003579), Rab11-related (InterPro:IPR015595); BEST Arabidopsis thaliana protein match is: RAB GTPase homolog A4C (TAIR:AT5G47960.1); Has 28921 Blast hits to 28882 proteins in 778 species: Archae - 24; Bacteria - 155; Metazoa - 15072; Fungi - 4263; Plants - 3370; Viruses - 20; Other Eukaryotes - 6017 (source: NCBI BLink). & (q40191|rb11a_lotja : 298.0) Ras-related protein Rab11A - Lotus japonicus & (reliability: 598.0) & (original description: no original description)
