Product Overview
This rabbit polyclonal antibody detects mitochondrial-processing peptidase subunit alpha (gene PMPCA) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 58.3 kDa, and the supplier reports an observed band at about 50–58 kDa.
PMPCA is the alpha subunit of the mitochondrial processing peptidase (MPP), located in the mitochondrial matrix. It recognizes and binds the N-terminal targeting sequences of newly imported precursor proteins, allowing the beta subunit to cut these presequences away. This processing step is required for most matrix proteins to mature, making PMPCA relevant to mitochondrial protein import research.

Immunogen
Recombinant human PMPCA/INPP5 fragment (Arg99–Arg525), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places mitochondrial-processing peptidase subunit alpha in the mitochondrion matrix and mitochondrion inner membrane. Tissue expression noted by UniProt (human): Ubiquitously expressed with highest expression in fetal tissues and adult brain, cerebellum and cerebellar vermis. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
