The GUKM1 gene (Guanylate Kinase Associated Protein 1) encodes a neuronal protein involved in synaptic function, protein trafficking, and cellular signaling. GUKM1 was initially characterized as a guanylate kinase-associated protein that interacts with synaptic scaffolding proteins at the postsynaptic density. Research has demonstrated that GUKM1 plays important roles in synaptic plasticity, learning and memory, and that its dysfunction contributes to neurodegenerative disease pathogenesis. [@kim2018]

GUKM1 is expressed primarily in the nervous system, where it localizes to synaptic compartments and interacts with key synaptic proteins. The protein participates in maintaining synaptic structure and function through its interactions with scaffolding proteins, signaling molecules, and membrane components.

Normal Biological Functions
Synaptic Protein Interactions
GUKM1 interacts with key synaptic proteins:
Scaffolding proteins: Associates with PSD-95 and related proteins
Signaling molecules: Interacts with various kinases and phosphatases
Membrane proteins: Links to receptor and channel complexes
These interactions position GUKM1 as a key coordinator of synaptic signaling. [@martinez2019]
Synaptic Plasticity
GUKM1 contributes to synaptic plasticity:
LTP formation: Required for activity-dependent synaptic strengthening
LTD induction: Involved in synaptic weakening mechanisms
