Generic protein structure example

NUAK family SNF1-like kinase 1 also known as AMPK-related protein kinase 5 (ARK5) is an enzyme that in humans is encoded by the NUAK1 gene.[1][2][3]

Function

Acts as a regulator of cellular senescence and cellular ploidy by mediating phosphorylation of 'Ser-464' of LATS1, thereby controlling its stability. Controls cell adhesion by regulating activity of the myosin protein phosphatase 1 (PP1) complex.[4]

Clinical significance

ARK5 is important in tumor malignancy and invasiveness.[5]

Research findings

ARK5 is often overexpressed in multiple myeloma cell lines.[6][7] ARK5 promotes tumor cell survival under regulation by Akt.[5]

ARK5 increases MT1-MMP production.[5] (MT1-MMP activates MMP-2 and MMP-9 which are involved in tumor metastasis.[5])

As a drug target

ON123300 (a CDK4 inhibitor), also inhibits ARK5 and reduces proliferation of multiple myeloma and mantle cell lymphoma cell lines.[6]

Interactions

NUAK1 has been shown to interact with USP9X[8] and Ubiquitin C.[8]
