IPGA1_ARATH | developmental stage | Highest levels observed in petals during late developmental stages. |
IPGA1_ARATH | function | Microtubule-associated protein involved in the regulation of anisotropic petal and cotyledons growth and shape by affecting cortical microtubule organization (PubMed:31198941, PubMed:31623377, PubMed:35975703). Prevents cortical microtubules organization into parallel arrays oriented perpendicular to the axis of cell elongation thus limiting anisotropic cell growth in the late phases of petal development (PubMed:31198941, PubMed:31623377, PubMed:35975703). Cooperatively with ANGUSTIFOLIA (AN), negatively regulates cortical microtubules (CMTs) organization in response to mechanical stress and modulates pavement cells morphogenesis leading to puzzle shape, probably in an AAA1/KTN1-dependent manner (PubMed:35975703). |
IPGA1_ARATH | similarity | Belongs to the IPGA1 family. |
IPGA1_ARATH | subcellular location | Colocalizes with cortical microtubules and binds directly to microtubules (PubMed:31198941, PubMed:35975703). In young pavement cells, observed as granules in the cytosol and at the cell periphery (PubMed:35975703). Formation to granules on microtubules is promoted by mechanical perturbations (PubMed:35975703). |
IPGA1_ARATH | tissue specificity | Expressed ubiquitously at all development stages, with highest in developing petals (PubMed:31198941). During mechanical stress, accumulates in granules on microtubules (PubMed:35975703). |
