Mitogen-activated protein kinase kinase kinase kinase 1 is a protein kinase that in humans is encoded by the MAP4K1 gene.[1]. It is also known as HPK1 (Hematopoietic Progenitor Kinase 1).

Interactions

MAP4K1 has been shown to interact with B-cell linker,[2] Grb2,[3][4][5][6] CRKL,[3][5][6] Drebrin-like,[7] CRK,[3][5][6] Linker of activated T cells,[6] NCK1[4][5][6] and GRAP2.[8]
