Background

NEK9, a pleiotropic regulator of mitotic progression, orchestrates critical processes in spindle dynamics and chromosome separation. Its pivotal role extends to phosphorylating various substrates, including histones, myelin basic protein, beta-casein, and BICD2. Specifically, NEK9 exhibits phosphorylation activity towards histone H3 on serine and threonine residues and beta-casein on serine residues. The multifaceted influence of NEK9 is underscored by its involvement in the G1/S transition and S phase progression. Moreover, NEK9 plays a key role in modulating the activity of NEK6 and NEK7, enhancing their functionality by releasing the autoinhibitory functions of Tyr-108 and Tyr-97, respectively. This comprehensive regulatory role emphasizes NEK9's significance in governing mitotic processes and ensuring the precise orchestration of cellular events during cell cycle progression.

Biological Activity

The activity was measured by off-chip mobility shift assay(MSA). The enzyme was incubated with fluorecence-labeled substrate and Mg(or Mn)/ATP. The phosphorylated and unphosphorylated substrates were separated and detected by MSA device. The KM of NEK9 is 54.69 µM

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
