Abstract
This family consists of several plant proteins, including protein OCTOPUS (OPS, At3g09070) and OPSL1 (At5g01170) from Arabidopsis [ 1 ]. OPS is a membrane-associated protein that regulates phloem differentiation entry [ 2 ]. It is a positive regulator of the brassinosteroid (BR) signaling pathway and sequesters BIN2 to the plasma membrane to promote phloem differentiation [ 3 ].
