Related Product Information for HPK1 active protein
HPK1 or Hematopoietic progenitor kinase 1 is a hematopoietic cell-restricted member of the Ste20 serine/threonine kinase super family. HPK1 is also known as mitogen-activated protein kinase kinase kinase kinase 1(MAP4K1). HPK1 is a tissue-specific upstream activator of the MEKK/JNK/SAPK signaling pathway. HPK1 diminishes T cell receptor (TCR) signaling activity and T cell proliferation by phosphorylating the adaptor protein SLP-76.

Uniprot Description

HPK1: a protein kinase of the STE20 family. Expressed primarily in hematopoietic organs, including bone marrow, spleen and thymus. Also expressed at very low levels in lung, kidney, mammary glands and small intestine. May play a role in hematopoietic lineage decisions and growth regulation. Positively regulated by PGE2 and a negative regulator of PGE2-induced FOS gene transcription.

Product Notes

The HPK1 map4k1 (Catalog #AAA4160171) is an Active Protein produced from Insect Cells and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "HPK1, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
