Active Recombinant Human HCK(230-497) Protein, N-His-tagged

• Cat.No.: HCK-98H
• Product Overview: N-terminal 6Histagged, recombinant, human Hck, amino acids 230–497, expressed by baculovirus in Sf21 insect cells. Purified using Ni2+/NTA agarose.

Specification

• Description: Hematopoietic cell kinase (HCK) is a member of Src protein-tyrosine kinase family and expressed primary in granulocytes, monocytes and macrophages. Active HCK phosphorylates STAT5B on Tyr699, which represents an essential step in Signal transducer and activator of transcription 5 (STAT5B) stimulation. The binding of SH3 ligands, such as the Nef protein of HIV-1, further augments Hck activity suggesting a new mechanism for regulating tyrosine kinase activity.
