What protein does LRRK2 code for?

The LRRK2 gene provides instructions for making a protein called dardarin. The LRRK2 gene is active in the brain and other tissues throughout the body. One segment of the dardarin protein is called a leucine-rich region because it contains a large amount of a protein building block (amino acid) known as leucine.

Is LRRK2 a protein?

LRRK2 is an unusually large protein (2527 amino acids) classified as a member of the ROCO superfamily which is characterized by the presence of tandem Ras of complex (Roc) G-domain, kinase domains and carboxy- terminal of Roc (COR) sequence which links them.

What chromosome is LRRK2 in?

The LRRK2 gene is situated on chromosome 12p11. 2–q13. 1 and encodes a large protein named dardarin. Dardarin contains several functional domains, including a leucine‐rich repeat domain, WD40, renin–angiotensin system/guanosine triphosphatases and kinase domains.

How does LRRK2 cause Parkinsons?

LRRK2 is involved in regulating responses in immune cells of the brain and further implicate microglial involvement in late-onset PD. Gillardon, F. Enhanced neuroinflammation may contribute to neurodegeneration in Parkinson’s disease patients carrying LRRK2 mutations.

How does LRRK2 cause Parkinson’s disease?

Where is LRRK2 expressed?

In summary, LRRK2 is constitutively expressed in neurons and also in glial cells of human brain. It strongly associates with pathological inclusions in several neurodegenerative disorders.

What is SNCA gene?

The SNCA gene provides instructions for making a small protein called alpha-synuclein. Alpha-synuclein is abundant in the brain, and smaller amounts are found in the heart, muscles, and other tissues.

What is a common leucine-rich repeat kinase 2 (lrk2) mutation?

A common leucine-rich repeat kinase 2 gene mutation in familial and sporadic Parkinson’s disease in Russia. Eur J Neurol. 2007;14:413–417. doi: 10.1111/j.1468-1331.2007.01685.x.

What is lrrk2-associated Parkinson’s disease?

LRRK2 is a large, widely expressed, multi-domain and multifunctional protein. LRRK2mutations are the major cause to inherited and sporadic PD. In this review, we discuss the pathology and clinical features which show diversity and variability of LRRK2-associated PD.

How does LRRK2 regulate its kinase domain?

In terms of how LRRK2 acts within the cell, the interplay between these two enzymatic functions is of great interest. Small GTPases such as Ras operate as molecular switches for associated kinases, and an attractive hypothesis is that the GTPase domain of LRRK2 acts to regulate its kinase domain.

How does LRRK2 mutation induce autophagic stress?

The LRRK2 p.R1441C mutation induced autophagic stress characterized by the accumulation of MVBs, abnormal AVs and skein-like cellular lesions. P.R1441C mutation in LRRK2 showed increased density of autophagic vacuoles in the brain cortex.
