peroxisomal membrane transport protein import into peroxisome matrix biological_process The import of proteins into the peroxisomal matrix. A peroxisome targeting signal (PTS) binds to a soluble receptor protein in the cytosol, and the resulting complex then binds to a receptor protein in the peroxisome membrane and is imported. The cargo protein is then released into the peroxisome matrix. peroxisome matrix protein import GO:0016558 protein transport to peroxisome matrix protein transmembrane import into intracellular organelle protein localization to peroxisome establishment of protein localization to peroxisome
