The world according to GARP

# # # #

Transportation of material inside of cells is a critical aspect of normal cellular functioning. Any disruption to this activity can cause significant problems.

An interesting aspect of recent genetic analysis work in Parkinson’s has been the number of genetic risk factors for the condition that are associated with cellular transportation activity.

Recently, researchers have discovered that one particular Parkinson’s-associated protein – LRRK2 – interacts with a cellular transport protein complex called GARP.

In today’s post, we will discuss what LRRK2 and GARP do and why their interaction is important.

John Irving is not everyone’s cup of tea, but I quite like his books (A Prayer for Owen Meany being my favourite).

In his fourth book (The World According to Garp), Irving wrote about about the life of T. S. Garp.

But it is his interactions with his wife and his mother’s friends & acquaintances that really make Garp’s unusual life a good read.

A young Robin Williams played Garp in the 1982 film adaptation of the book:

But what does this have to do with Parkinson’s?

Well, recently in the field of Parkinson’s research, the interactions of different kind of GARP have made for good reading.

What do you mean?
