DOCK Antibodies

DOCK (Dedicator of Cytokinesis) proteins are a family of guanine nucleotide exchange factors (GEFs) that activate small GTPases, primarily Rac and Cdc42, which are involved in regulating actin cytoskeleton dynamics, cell migration, and other cellular processes related to cytokinesis and morphogenesis. 

Content on DOCK Antibodies

DOCK antibodies specifically bind to the various isoforms of DOCK proteins, enabling the study of their roles in GTPase signaling pathways. These antibodies are applied in techniques such as Western blotting, immunoprecipitation, immunofluorescence, and co-immunoprecipitation to assess the localization, expression, and interaction of DOCK proteins with other molecules. Since DOCK proteins regulate actin cytoskeleton reorganization, DOCK antibodies are instrumental in studying how cells undergo morphological changes, particularly during cell migration and immune responses.

Applications of DOCK Antibodies

• Cell Migration and Cytoskeleton Dynamics: DOCK proteins act as GEFs for Rac and Cdc42, which are key regulators of actin polymerization and cell migration. DOCK antibodies are used to study how these proteins facilitate the rearrangement of the actin cytoskeleton during processes such as wound healing, cell motility, and invasion. 
• Immune Cell Activation and Function: DOCK proteins, such as DOCK2, play a critical role in the activation and migration of immune cells, including lymphocytes and neutrophils. DOCK antibodies are used to investigate how these proteins regulate immune cell chemotaxis and responses to inflammatory signals.
• Cancer Research: Dysregulation of DOCK proteins, particularly DOCK1 and DOCK5, is associated with cancer progression and metastasis. DOCK antibodies are employed to study how these proteins influence tumor cell invasion and metastasis by regulating the cytoskeleton and cell adhesion.
• Neuronal Development and Function: In the nervous system, DOCK proteins are involved in neuronal migration and axon guidance. DOCK antibodies are used to study the role of these proteins in neuronal development and synaptic plasticity. 
• Actin Polymerization Studies: DOCK proteins are essential for triggering actin polymerization through the activation of Rac and Cdc42. DOCK antibodies are used to explore how these proteins regulate actin dynamics during cellular processes that require cytoskeletal remodeling.

In conclusion, DOCK antibodies are essential tools for studying cell migration, immune cell function, cancer metastasis, and neuronal development. Their broad applications in cytoskeleton dynamics, signal transduction, and cell polarity make them invaluable for understanding how cells adapt to their environments and how dysregulation of these processes leads to disease.
