Recombinant Human TDGF1/CRIPTO Protein: Structure, Activity, and Applications

Introduction

Recombinant proteins are proteins that are produced through genetic engineering techniques, allowing for the production of large quantities of specific proteins with high purity and consistency. One such recombinant protein is the human TDGF1/CRIPTO protein, which has been extensively studied for its structure, activity, and potential applications in various fields.

Structure of Recombinant Human TDGF1/CRIPTO Protein

The human TDGF1/CRIPTO protein, also known as teratocarcinoma-derived growth factor 1 or cripto-1, is a glycoprotein that belongs to the epidermal growth factor (EGF) family. It is encoded by the TDGF1 gene and is composed of 188 amino acids with a molecular weight of 21 kDa. The recombinant form of this protein is produced in various expression systems, such as bacteria, yeast, and mammalian cells, and can be purified to high levels of homogeneity.

The crystal structure of recombinant human TDGF1/CRIPTO protein has been determined, revealing a compact globular structure with three disulfide bonds and a conserved EGF-like domain. The protein also contains a hydrophobic pocket that is believed to be involved in its biological activity.
