Overview
This page provides comprehensive information about this protein. See the content below for detailed information.
LIS1 (also known as PAFAH1B1) is a microtubule-associated protein that regulates dynein function and is essential for neuronal migration. It is the most common cause of isolated lissencephaly sequence.
Structure
LIS1 has a characteristic structure:
N-terminal dimerization domain - forms functional dimers
WD40 repeat domain (x7) - β-propeller for protein interactions
Dynein binding site - engages dynein heavy chain
Phosphorylation sites - regulatory control
Nistrin homology domain - unique to LIS1 family
The WD40 domain forms a 7-bladed β-propeller that serves as a protein interaction platform.
Normal Function
In [neurons](/entities/neurons), LIS1 performs essential functions:
Dynein regulation - modulates dynein motor activity
Clinical features - severe developmental delay, seizures
Motor deficits - hypotonia progressing to spasticity
Age of presentation - infancy
Prognosis - severe intellectual disability
Miller-Dieker Syndrome
Chromosomal deletion including LIS1
Lissencephaly plus facial dysmorphism
More severe phenotype
Early death common
Subcortical Band Heterotopia
Often with LIS1 mutations
Milder brain malformation
Better developmental outcome
Neurodegeneration
LIS1 in adult brain function
Altered expression in AD
Role in axonal transport deficits
