The cyclin D1 carboxyl regulatory domain controls the division and differentiation of hematopoietic cells
Background: The family of D cyclins has a fundamental role in cell cycle progression, but its members (D1, D2, D3) are believed to have redundant functions. However, there is some evidence that contradicts the notion of mutual redundancy and therefore this concept is still a matter of debate. Result...
