Recombinant Human STAU1 Protein, N-His

Introduction to Recombinant Human STAU1 Protein

Recombinant Human STAU1 Protein, also known as Staufen homolog 1 (STAU1), is a protein that plays a crucial role in RNA metabolism and transport. It is a member of the Staufen family of proteins, which are evolutionarily conserved and present in a wide range of organisms, from plants to humans.

Structure of Recombinant Human STAU1 Protein

Recombinant Human STAU1 Protein is a 59 kDa protein composed of 557 amino acids. It contains several domains, including three double-stranded RNA-binding domains (dsRBDs) and a microtubule-binding domain (MBD). The dsRBDs are responsible for binding to RNA, while the MBD binds to microtubules, allowing STAU1 to transport RNA molecules along these structures.

The protein structure of Recombinant Human STAU1 is highly conserved among different species, indicating its importance in cellular functions. It has been shown to interact with various other proteins, including RNA-binding proteins and translation initiation factors, further highlighting its role in RNA metabolism and transport.

Activity of Recombinant Human STAU1 Protein

The main activity of Recombinant Human STAU1 Protein is its role in RNA transport and localization. It binds to specific RNA molecules, such as mRNAs, and transports them to their designated locations within the cell. This process is crucial for proper cellular function, as it ensures that the right proteins are produced in the right place and at the right time.

In addition to its role in RNA transport, Recombinant Human STAU1 Protein also plays a role in RNA stability. It has been shown to protect certain mRNAs from degradation, thereby regulating their levels in the cell. This activity is particularly important in cells that require precise control over gene expression, such as neurons.
