Product Specs

Introduction
HHEX is a member of the homeobox protein family of transcription factors, which plays a crucial role in developmental processes. It is known to interact with the Promyelocytic leukemia protein. Its expression in specific hematopoietic cell lines suggests its involvement in hematopoietic differentiation.
Description
Recombinant HHEX protein, expressed in E.coli, is a single, non-glycosylated polypeptide chain. It consists of 293 amino acids (residues 1-270) and has a molecular weight of 32.4kDa. The protein includes a 23 amino acid His-tag fused at the N-terminus. Purification is achieved using proprietary chromatographic techniques.
Physical Appearance
A clear and colorless solution, sterilized by filtration.
Formulation
The HHEX solution is supplied in a buffer containing 20mM Tris-HCl (pH 8.0), 0.15M NaCl, 1mM DTT, and 40% glycerol.
Stability
For short-term storage (2-4 weeks), the product should be kept at 4°C. For extended storage, freeze the solution at -20°C. The addition of a carrier protein (0.1% HSA or BSA) is recommended for long-term storage. Repeated freezing and thawing cycles should be avoided.
Purity
The purity is determined to be greater than 85% using SDS-PAGE analysis.

Product Science Overview

Introduction

The Hematopoietically Expressed Homeobox (HHEX) gene, also known as HEX, PRH (Proline-Rich Homeodomain), or XHEX in Xenopus, is a non-clustered homeobox gene that plays a crucial role in various biological processes. This gene is evolutionarily conserved across species, including fish, amphibians, birds, mice, and humans .

Gene Structure and Location

The human HHEX gene is located on chromosome 10 and comprises four exons . In mice, it is located on chromosome 19 . The gene encodes a transcription factor that is essential for the regulation of embryogenesis and hematopoietic progenitor development .

Biological Functions

HHEX is a transcriptional repressor involved in several critical developmental processes:

  1. Embryogenesis: HHEX is vital for the development of the foregut endoderm, which gives rise to endocrine organs such as the pancreas . It is also necessary for the normal development of the bile duct and liver, the latter being the initial site of hematopoiesis .
  2. Hematopoiesis: HHEX governs the origins of hematopoietic cells and is crucial for the self-renewal of definitive hematopoietic stem cells (HSCs) and lymphopoiesis .
  3. Endocrine System: HHEX is required for the development of the forebrain and thyroid gland, and its dysfunction is linked to various endocrine disorders .
Clinical Significance

HHEX has been identified as a promising candidate gene for type 2 diabetes through genome-wide association studies . Polymorphisms in the HHEX gene, such as rs1111875, rs5015480, and rs7923837, have been associated with an increased risk of type 2 diabetes . Additionally, HHEX is implicated in various hematological malignancies and other diseases .

Research and Therapeutic Potential

The recombinant form of HHEX (Human Recombinant) is used in research to study its functions and potential therapeutic applications. Understanding the role of HHEX in various biological processes and diseases can lead to the development of targeted therapies for conditions such as diabetes, hematological malignancies, and endocrine disorders .
