Yes1 — Proto-Oncogene Tyrosine-Protein Kinase Yes1

Yes1 — Proto-Oncogene Tyrosine-Protein Kinase Yes1

Introduction

Yes1 — Proto Oncogene Tyrosine Protein Kinase Yes1 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

Yes1 (Proto-Oncogene Tyrosine-Protein Kinase Yes1) is a member of the Src family of non-receptor tyrosine kinases (SFKs). It is a 60 kDa non-receptor tyrosine kinase that is widely expressed in tissues including brain, lung, and testis. Yes1 participates in signaling pathways controlling cell proliferation, differentiation, and epithelial-mesenchymal transition. [@src]

Structure

The Yes1 protein is a member of the Src family of non-receptor tyrosine kinases (SFKs). The structure consists of:

• N-terminal myristoylation site for membrane anchoring
• Unique domain (specific to each SFK member)
• SH3 domain (proline-rich motif binding)
• SH2 domain (phosphotyrosine binding)
• Catalytic tyrosine kinase domain
• C-terminal regulatory tyrosine

Structure

The Yes1 protein is a member of the Src family of non-receptor tyrosine kinases (SFKs). The structure consists of:

• N-terminal myristoylation site for membrane anchoring
• Unique domain (specific to each SFK member)
• SH3 domain (proline-rich motif binding)
• SH2 domain (phosphotyrosine binding)
• Catalytic tyrosine kinase domain
• C-terminal regulatory tyrosine

Normal Function

Yes1 is a non-receptor tyrosine kinase that regulates multiple signaling pathways:

• Receptor signaling: Activated by growth factor receptors, integrin receptors, and immune receptors
• Synaptic function: Phosphorylates [NMDA](/entities/nmda-receptor) receptor subunits, PSD-95, and other synaptic proteins
• Cellular processes: Regulates cell proliferation, differentiation, survival, migration, and cytoskeletal organization

Role in Disease

Dysregulated Yes1 activity contributes to:

• Alzheimer's Disease: Altered phosphorylation of [tau](/proteins/tau) and [amyloid precursor protein](/entities/app-protein) processing
• Parkinson's Disease: Involved in dopaminergic neuron signaling and survival
• Cancer: Constitutively active in various cancers

Therapeutic Targeting

Yes1-targeted therapies include:

• Multi-kinase inhibitors: Dasatinib, bosutinib, saracatinib
• Selective inhibitors: Yes1-specific compounds in development
• Combination approaches: With amyloid or [tau](/proteins/tau)-targeted therapies for AD
