Specifically binds 5-hydroxymethylcytosine (5hmC), suggesting that it acts as a specific reader of 5hmC. Expressed in the medulla containing mature thymocytes, but not the cortex having immature thymocytes (at protein level). Abundant expression seen in testis, liver, brain and kidney with lower levels of the expression in thymus, spleen, heart and stomach. Down-regulated upon induction of apoptosis. Phosphorylated.
