ABR — Arabidopsis thaliana

Summary

AT2G34650, also known as ABR, PID, or PINOID, encodes a non-specific serine/threonine protein kinase with protein serine/threonine kinase activity, calmodulin binding, calcium ion binding, mRNA binding, and cis-trans proline isomerase activity. This gene is associated with basipetal auxin transport, response to gravity, perianth, style, stigma, and vasculature development, dehiscence, transcytosis, and intercellular transport. It is linked to traits such as inflorescence size, phyllotaxy, stamen number and length, style length, root length, adventitious root number, cotyledon morphology, auxin content and sensitivity, and osmotic response sensitivity. The protein localizes to the apical plasma membrane, plasmodesma, plant-type vacuole, nucleus, cytosol, and mitochondria.
