Description of Recombinant Human MICOS13 Protein, N-His-SUMO

Introduction to Recombinant Human MICOS13 Protein

Recombinant Human MICOS13 Protein, also known as Mitochondrial Contact Site and Cristae Organizing System Subunit 13, is a protein that plays a crucial role in maintaining the structure and function of mitochondria. It is a highly conserved protein found in various species, including humans, and is encoded by the MICOS13 gene.

Structure of Recombinant Human MICOS13 Protein

The recombinant form of MICOS13 is a 16 kDa protein with a molecular weight of 144 amino acids. It consists of two transmembrane domains, a coiled-coil domain, and a C-terminal domain. The N-terminal domain is responsible for anchoring the protein to the inner mitochondrial membrane, while the C-terminal domain interacts with other MICOS subunits to form the mitochondrial contact site and cristae organizing system (MICOS) complex.

The MICOS complex is a multi-protein complex that is essential for maintaining the structure and function of mitochondria. It is responsible for organizing the inner mitochondrial membrane into cristae, which are necessary for efficient oxidative phosphorylation. The MICOS13 protein is a crucial component of this complex and is involved in stabilizing the structure of cristae and promoting the formation of contact sites between the inner and outer mitochondrial membranes.

Activity of Recombinant Human MICOS13 Protein

The primary function of MICOS13 is to maintain the structural integrity of mitochondria. It achieves this by forming contact sites between the inner and outer mitochondrial membranes, which allow for efficient communication and transport of molecules between these two compartments. The protein also plays a role in organizing the inner mitochondrial membrane into cristae, which are essential for the proper functioning of the electron transport chain and ATP production.

Studies have shown that MICOS13 is involved in regulating the size and shape of cristae, as well as their distribution within the mitochondrial matrix. It achieves this by interacting with other MICOS subunits and forming a scaffold-like structure that supports the cristae. Additionally, MICOS13 has been found to play a role in maintaining the balance of lipids in the inner mitochondrial membrane, which is crucial for maintaining membrane integrity and function.
