General Information

Description Auxin efflux carrier, Probable auxin efflux carrier component 1c (OsPIN1c) - Oryza sativa (Rice), Encodes an auxin efflux carrier involved in shoot and root development. It is involved in the maintenance of embryonic auxin gradients. Loss of function severely affects organ initiation, pin1 mutants are characterised by an inflorescence meristem that does not initiate any flowers, resulting in the formation of a naked inflorescence stem. PIN1 is involved in the determination of leaf shape by actively promoting development of leaf margin serrations. In roots, the protein mainly resides at the basal end of the vascular cells, but weak signals can be detected in the epidermis and the cortex. Expression levels and polarity of this auxin efflux carrier change during primordium development suggesting that cycles of auxin build-up and depletion accompany, and may direct, different stages of primordium development. PIN1 action on plant development does not strictly require function of PGP1 and PGP19 proteins. | PIN-FORMED 1 (PIN1) | FUNCTIONS IN: transporter activity | INVOLVED IN: in 14 processes | LOCATED IN: apical part of cell, plasma membrane, membrane, basal plasma membrane, cytoplasm | EXPRESSED IN: 25 plant structures | EXPRESSED DURING: 13 growth stages | CONTAINS InterPro DOMAIN/s: Auxin efflux carrier, subgroup , Auxin efflux carrier | BEST Arabidopsis thaliana protein match is: Auxin efflux carrier family protein
