Putative regulator of 1,3-beta-glucan biosynthesis; interacts with the catalytic (Fks1p and Gsc2p) and regulatory subunits (Rho1p) of 1,3-beta-glucan synthase; has a negative genetic interaction with RHO1; localizes to the cell periphery during early G1, to the bud tip in late G1, to the bud at S/G2, to the periphery of the bud at metaphase and at the bud neck during telophase; periodically expressed during the cell cycle; protein abundance increases in response to DNA replication stress
