Peroxisomal membrane protein; membrane receptor for peroxisome retention factor Inp1p, which together form an ER‐peroxisome junction to tether the organelle at the cortex; membrane anchor involved in the recruitment of myosin V adaptor and inheritance factor Inp2p to regulate peroxisomal partitioning; regulated by phosphorylation of a membrane loop by Slt2p in response to fatty acid-containing media that stimulates peroxisomal proliferation; required for proper localization and stability of PMPs
