LociOiling's phosphotransferase from puzzle 1038.

54: Human Fyn 2 is a revisiting puzzle, originally presented in 2009 as Puzzle 54: Human Fyn 2.

The puzzle protein is an enzyme, a type of phosphotransferase, specifically a kinase. This human protein is encoded by a gene known as FYN, and controls cell growth. It interacts with a long list of other proteins. Overexpression of this protein has been linked to several forms of cancer.

The puzzle has 59 segments with the sequence:
