Recombinant Human KRAS Protein (1-186aa), N-His tagged

• Cat.No.: KRAS-33H
• Product Overview: Recombinant human KRAS protein (1-186aa), fused to His-tag at N-terminus, was expressed in E. coli and purified by using conventional chromatography.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: 1-186aa
• Description: This gene, a Kirsten ras oncogene homolog from the mammalian ras gene family, encodes a protein that is a member of the small GTPase superfamily. A single amino acid substitution is responsible for an activating mutation. The transforming protein that results is implicated in various malignancies, including lung adenocarcinoma, mucinous adenoma, ductal carcinoma of the pancreas and colorectal carcinoma. Alternative splicing leads to variants encoding two isoforms that differ in the C-terminal region.
