Overview

Description

  • Nature
    Recombinant
  • Source
    Escherichia coli
  • Amino Acid Sequence
    • Species
      Cow

Specifications

Our Abpromise guarantee covers the use of ab60893 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • Applications

    Functional Studies

  • Purity
    > 95 % SDS-PAGE.

  • Form
    Liquid
  • Additional notes
    This product is supplied as 1 vial containing ~0.2units of protein.


    This protein can be used for fusion protein cleavage. The rare 5 amino acid recognition sequence of the enterokinase cleavage site is incorporated into a tag with the sequence: N-Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys-C Cleavage by enterokinase removes the tag from the fusion protein.

  • Function
    Responsible for initiating activation of pancreatic proteolytic proenzymes (trypsin, chymotrypsin and carboxypeptidase A). It catalyzes the conversion of trypsinogen to trypsin which in turn activates other proenzymes including chymotrypsinogen, procarboxypeptidases, and proelastases.
  • Tissue specificity
    Intestinal brush border.
  • Involvement in disease
    Defects in TMPRSS15 are a cause of enterokinase deficiency (ENTKD) [MIM:226200]; a life-threatening intestinal malabsorption disorder characterized by diarrhea and failure to thrive.
  • Sequence similarities
    Belongs to the peptidase S1 family.
    Contains 2 CUB domains.
    Contains 2 LDL-receptor class A domains.
    Contains 1 MAM domain.
    Contains 1 peptidase S1 domain.
    Contains 1 SEA domain.
    Contains 1 SRCR domain.
  • Post-translational
    modifications
    The chains are derived from a single precursor that is cleaved by a trypsin-like protease.
  • Cellular localization
    Membrane.
  • Information by UniProt
