Human OPA1 Recombinant Protein (N-His) (GXRP00191)

Human OPA1 Recombinant Protein (N-His)

Human OPA1 Recombinant Protein (N-His) is a recombinant protein expressed in E. coli, spanning Ser607-Lys960, with an N-terminal His tag. Predicted molecular weight: 44.48 kDa. Purity: >80% as determined by SDS-PAGE. Supplied lyophilized from a solution in PBS pH 7.4, 0.02% NLS, 1 mM EDTA, 4% Trehalose, 1% Mannitol. Applications: ELISA, immunogen, SDS-PAGE and Western blot. Dynamin-like GTPase OPA1, mitochondrial is a ~111 kDa protein. Dynamin-related GTPase that is essential for normal mitochondrial morphology by mediating fusion of the mitochondrial inner membranes, regulating cristae morphology and maintaining respiratory chain function. For research use only.

Exists in two forms: the transmembrane, long form (Dynamin-like GTPase OPA1, long form; L-OPA1), which is tethered to the inner mitochondrial membrane, and the short soluble form (Dynamin-like GTPase OPA1, short form; S-OPA1), which results from proteolytic cleavage and localizes in the intermembrane space. Both forms (L-OPA1 and S-OPA1) cooperate to catalyze the fusion of the mitochondrial inner membrane. The equilibrium between L-OPA1 and S-OPA1 is essential: excess levels of S-OPA1, produced by cleavage by OMA1 following loss of mitochondrial membrane potential, lead to an impaired equilibrium between L-OPA1 and S-OPA1, inhibiting mitochondrial fusion. The balance between L-OPA1 and S-OPA1 also influences cristae shape and morphology.
