CASIS PCG 16

iss058e002064 (1/6/2019) --- CASIS PCG 16 floating in front of Window 7 in the Cupola module. Earth is in the background. Crystallization of LRRK2 Under Microgravity Conditions-2 (CASIS PCG 16) evaluates growth of Leucine-rich repeat kinase 2 (LRRK2) protein crystals in microgravity. LRRK2 is implicated in Parkinson’s disease, but crystals of the protein grown on Earth are too small and compact to study. Detailed analysis of larger, space-grown crystals can define the protein’s exact shape and morphology and help scientists better understand the disease’s pathology.
