Casein Kinase 2-A Kinase that Inhibits Brown Fat Formation

In adipose tissue, there is a delicate balance between storing and expending energy. In this issue, Shinoda et al. (2015) use phosphoproteomics to identify casein kinase 2 (CK2) as a suppressor of brown adipocyte formation, providing insights into how adipose tissue regulates its composition of white versus brown adipocytes.
