DatasheetSpecific ReferencesReviewsRelated ProductsProtocols
Human MAP1D Protein Product Information
Protein Construction:A DNA sequence encoding the human MAP1D (NP_954697.1) (Arg 44-Ala 335) was expressed, with an initial Met at the N-terminus and a polyhistidine tag at the C-terminus.
Expressed Host:Baculovirus-Insect Cells
Shipping:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Human MAP1D Protein QC Testing
Purity:> 92 % as determined by SDS-PAGE
Bio-Activity:Measure by its ability to remove methionine from a fluorogenic peptide substrate H-Met-Gly-Pro-AMC, R&D Systems, Catalog#ES017. The resulting GP-AMC is cleaved by human DPPIV/CD26, R&D Systems, Catalog#1180SE . The specific activity is >30 pmoles/min/μg .
Endotoxin:< 1.0 EU per μg of the protein as determined by the LAL method
Stability:Samples are stable for up to twelve months from date of receipt at -70℃
Predicted N Terminal:Met
Molecule Mass:The secreted recombinant human MAP1D consists of 303 amino acids and predicts a molecular mass of 33.4 kDa. It migrates as an approximately 36 kDa band in SDS-PAGE under reducing conditions.
Formulation:Lyophilized from sterile 50mM Tris, 100mM NaCl, pH 8.0
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
Human MAP1D Protein Usage Guide
Storage:Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution:A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

MAP1D Background

Methionine aminopeptidase 1D, also known as MAP1D, is a member of the peptidase M24A family. N-terminal methionine removal is an important cellular process required for proper biological activity, subcellular localization, and eventual degradation of many proteins. The enzymes that catalyze this reaction are called Methionine aminopeptidases (MAPs). MAP1D is overexpressed in colon cancer cell lines and colon tumors as compared to normal tissues (at protein level). Downregulation of MAP1D expression by shRNA in HCT-116 colon carcinoma cells reduces anchorage-independant growth in soft agar. MAP1D binds two cobalt ions per subunit. The true nature of the physiological cofactor is under debate. MAP1D is also active with zinc, manganese or divalent ions. MAP1D removes the amino-terminal methionine from nascent proteins. It may also play an important role in colon tumorigenesis.
