Recombinant Human RAB Interacting Factor, His-tagged

• Cat.No.: RABIF-2799H
• Product Overview: Recombinant human RABIF protein (1-123 aa), fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: 1-123 a.a.
• Description: RABIF, also known as guanine nucleotide exchange factor MSS4, is a guanine-nucleotide-releasing protein that may participate in vesicular transport. This protein stimulates GTP-GDP exchange in Sec4 and Rab and binds to a subset of genetically related Rab proteins.
