Modeling the Structural Consequences of BEST1 Missense Mutations
... The majority of the disease-causing missense mutations identified in humans affect folding or trafficking, rather than specifically affecting protein function (Sanders and Myers 2004). To date, all examined missense changes in the hBest1 were associated with functional consequences, implicating an i ...
