PHOT2 | Phototropin-2; Protein kinase that acts as a blue light photoreceptor in a signal-transduction pathway for photo-induced movements. Phosphorylates BLUS1, a kinase involved in stomatal opening. Mediates calcium spiking of extra- and intracellular origins in response to blue light. Involved in hypocotyl phototropism. Contributes to the chloroplast accumulation in low blue light and mediates their translocation (avoidance response) at high fluence. Regulates stomata opening and photomorphogenesis response of leaf tissue. Not involved in hypocotyl elongation inhibition, anthocyanin accumul [...] (915 aa) | ||||
ARC5 | Dynamin-like protein ARC5; Probable GTPase component of both plastid and peroxisme division machinery. Required for the last steps of plastid division specifically in mesophyll-cell, when the narrow isthmus breaks, facilitating the separation of the daughter plastids. Necessary for peroxisome activities. Seems to influence stromule (stroma-filled tubular extensions of the plastid envelope membrane) length and frequency. Belongs to the TRAFAC class dynamin-like GTPase superfamily. Dynamin/Fzo/YdjA family. (777 aa) | ||||
PDV1 | Plastid division protein PDV1; Component of the plastid division machinery. Required to mediate the recruitment of ARC5 at the midplastid constriction site in the cytoplasm. (272 aa) | ||||
PDV2 | Plastid division protein PDV2; Component of the plastid division machinery. Required to mediate the recruitment of ARC5 at the midplastid constriction site in the cytoplasm. Relays plastid division site position between stroma and outer surface via interactions with the cytoplasmic ARC5 and the inner membrane ARC6 that recruits stromal FtsZ ring. (307 aa) |
