Recombinant Human RAB12 Protein, N-His

Introduction

Recombinant Human RAB12 Protein is a highly purified, bioactive protein that plays a crucial role in various cellular processes. It is a member of the RAS superfamily of small GTPases and is involved in regulating intracellular vesicle trafficking and membrane dynamics. In this article, we will discuss the structure, activity, and applications of this important protein.

Structure of Recombinant Human RAB12 Protein

Recombinant Human RAB12 Protein is a 25-kDa protein with a conserved GTP-binding domain and a C-terminal hypervariable region. It is composed of 202 amino acids and shares high sequence homology with other members of the RAB family. The protein has a globular structure with a central β-sheet surrounded by α-helices. The GTP-binding domain, also known as the switch region, is responsible for the protein’s activity and is highly conserved among all RAB proteins.

Activity of Recombinant Human RAB12 Protein

Recombinant Human RAB12 Protein is a key regulator of intracellular vesicle trafficking and membrane dynamics. It is localized to the Golgi complex and endosomes and plays a crucial role in the transport of cargo between these compartments. The protein functions as a molecular switch, cycling between an active GTP-bound state and an inactive GDP-bound state. In its active state, RAB12 recruits effector proteins to the membrane, which mediate various cellular processes such as vesicle formation, fusion, and transport.
