Leucine-rich repeat kinase 2 (LRRK2), a large and complex protein that possesses two enzymatic properties, kinase and GTPase, is one of the major genetic factors in Parkinson's disease (PD). Here, we characterize the kinetic and catalytic mechanisms of truncated wild-type (t-wt) LRRK2 and its most common mutant, G2019S (t-G2019S), with a structural(More)
The effect of leucine-rich repeat kinase 2 (LRRK2) mutation I2020T on its kinase activity has been controversial, with both increased and decreased effects being reported. We conducted steady-state and pre-steady-state kinetic studies on LRRKtide and its analog LRRKtide(S). Their phosphorylation differs by the rate-limiting steps: product release is(More)
Collaborative learning has become a dominant learning apparatus for higher level learning objectives. Much of the psychological and social mechanisms operating under this complex group activity, however, is not yet well understood. The purpose of this study was to investigate the effects of college students' communication competence and degree centralities(More)
BACKGROUND Dyschromias are becoming a more common concern among patients, particularly among persons of color. There are a variety of treatments, including more novel agents for dyschromias. Evaluating common agents prescribed among various races may prompt efforts to enhance care for dyschromias in patients of color. OBJECTIVE To determine whether racial(More)
