A
RasGap-related protein. A single CH domain exists in Vav (Adams
et al, 1992) and this has been suggested as
being the actin-binding region of Vav (Castresana
& Saraste, 1995). The CH (calponin homology)
domain is found usually in tandem in actin binding proteins. However, it
is generally been found that a single CH domain is insufficient for actin
binding (Gimona & Mittal, 1998).
