DDR1 Protein, Human (HEK293, His)

Cat. No.: HY-P75305
COA Handling Instructions

The DDR1 protein is a tyrosine kinase and cell surface receptor for fibrillar collagen that tightly regulates cell attachment and affects extracellular matrix processes. Upon collagen binding, DDR1 initiates a signaling cascade involving SRC, activating MAP kinase. DDR1 Protein, Human (HEK293, His) is the recombinant human-derived DDR1 protein, expressed by HEK293 , with C-His labeled tag. The total length of DDR1 Protein, Human (HEK293, His) is 398 a.a., with molecular weight of 55-70 kDa.

Description

The DDR1 protein is a tyrosine kinase and cell surface receptor for fibrillar collagen that tightly regulates cell attachment and affects extracellular matrix processes. Upon collagen binding, DDR1 initiates a signaling cascade involving SRC, activating MAP kinase. DDR1 Protein, Human (HEK293, His) is the recombinant human-derived DDR1 protein, expressed by HEK293 , with C-His labeled tag. The total length of DDR1 Protein, Human (HEK293, His) is 398 a.a., with molecular weight of 55-70 kDa.

Background

DDR1 protein serves as a tyrosine kinase and functions as a cell surface receptor for fibrillar collagen, playing a pivotal role in regulating cell attachment to the extracellular matrix and influencing processes such as extracellular matrix remodeling, cell migration, differentiation, survival, and proliferation. Upon collagen binding, DDR1 initiates a signaling cascade involving SRC and activates MAP kinases. This activation, in turn, leads to the up-regulation of matrix metalloproteinases MMP2, MMP7, and MMP9, facilitating extracellular matrix remodeling and promoting cell migration and wound healing. DDR1's significance extends to various physiological processes, including normal blastocyst implantation during pregnancy, mammary gland differentiation, lactation, and the maintenance of ear morphology and hearing. Additionally, DDR1 contributes to arterial wound healing by promoting smooth muscle cell migration and plays a role in tumor cell invasion, further underscoring its diverse functional repertoire. Notably, DDR1 phosphorylates PTPN11 as part of its regulatory activities.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
