Description of YDR244W: Peroxisomal membrane signal receptor for the C-terminal tripeptide signal sequence (PTS1) of peroxisomal matrix proteins, required for peroxisomal matrix protein import; also proposed to have PTS1-receptor independent functions[1][2][3][4]

Other Topic: Homology

Homology was found, at the sequence and domain-composition level, between several components of the Peroxisomal protein import machinery and components of the Endoplasmic Reticulum Associated Decay (ERAD) pathway. This suggests a common evolutionary origin for both systems and a similar mechanism of action. The homology relationships can be stablished between Pex1,Pex6 and cdc48; Pex2 and Hrd1; Pex4 and Ubc1; and Pex5 and Hrd3. [5] [6]
