What is HP1 and how does it function?
What will be an ideal response?
Ans: HP1 (now known as HP1?) is a mammalian protein that plays an important role in the formation of heterochromatin. It contains a chromodomain that binds to methylated H3. The binding of one HP1 triggers self-aggregation, the binding of additional HP1 molecules that extends the inactive region.
