Mcph1 Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Overview
This page provides comprehensive information about this protein. See the content below for detailed information.
MCPH1 (also known as BRIT1) is a DNA damage response protein critical for proper brain development. Mutations cause primary microcephaly, a condition characterized by significantly reduced head circumference due to impaired neurogenesis.
Structure
MCPH1 has several key structural features:
N-terminal BRCT domains (x2) - DNA damage response
BRC1-like domain - regulates BRCT function
Chromatin binding domain - mediates chromatin association

MCPH1 (also known as BRIT1) is a DNA damage response protein critical for proper brain development. Mutations cause primary microcephaly, a condition characterized by significantly reduced head circumference due to impaired neurogenesis.
Structure
MCPH1 has several key structural features:
N-terminal BRCT domains (x2) - DNA damage response
BRC1-like domain - regulates BRCT function
Chromatin binding domain - mediates chromatin association
Phosphorylation sites - ATM/ATR target sites
Nuclear localization signal - nuclear import
The protein functions as a scaffold for DNA repair proteins.
Normal Function
During brain development, MCPH1 performs critical functions:
DNA damage response - activates checkpoint signaling
Early intervention - critical period for treatment
