Overview

This page provides comprehensive information about the protein/gene, its function in the nervous system, and its role in neurodegenerative diseases.

Function

CCDC88A, also known as Girdin (G protein-interacting protein, also called Akt1/PKB interacting protein), is an actin-binding protein that plays critical roles in cytoskeletal dynamics, cell migration, and intracellular signaling.

Key functions include:

• Actin cytoskeleton regulation: Modulates actin filament assembly and organization
• Cell migration: Essential for neuronal migration during development
• [Autophagy](/entities/autophagy) regulation: Interacts with autophagy machinery
• Signal transduction: Modulates PI3K/Akt signaling pathway
• Synaptic plasticity: Involved in dendritic spine formation and function

Girdin is highly expressed in the developing brain and continues to be expressed in adult neurons, particularly in the [hippocampus](/brain-regions/hippocampus) and cerebral [cortex](/brain-regions/cortex).

Disease Associations

| Disease | Evidence | Mechanism |
|---------|----------|-----------|
| [Alzheimer's Disease](/diseases/alzheimers-disease) | GWAS, expression studies | Impaired autophagy, synaptic dysfunction |
| [Parkinson's Disease](/diseases/parkinsons-disease) | Genetic associations | [Alpha-synuclein](/proteins/alpha-synuclein) interaction |
| ALS | Expression studies | Motoneuron vulnerability |

CCDC88A variants have been associated with neurodegenerative diseases through its roles in protein quality control, cytoskeletal integrity, and cell survival pathways.

Expression

CCDC88A is expressed in:

• Brain (hippocampus, cerebral cortex, cerebellum)
• [Neurons](/entities/neurons) (pyramidal neurons, Purkinje cells)
• [Astrocytes](/entities/astrocytes)
• Developing nervous system (highest during neurogenesis)

Research Directions

Research Directions

Research on CCDC88A/Girdin in neurodegeneration focuses on its role in actin cytoskeleton dynamics and autophagy. The protein's involvement in AMPA receptor trafficking suggests potential therapeutic applications for synaptic dysfunction in AD^[6]. Modulators of CCDC88A phosphorylation state are being investigated as potential neuroprotective agents.

The intersection of CCDC88A function with neurotrophin signaling pathways provides additional therapeutic opportunities. Understanding how CCDC88A integrates signals from BDNF and other growth factors may reveal novel approaches for promoting neuronal survival^[7].
