SPAC6G10.10c Antibody

Introduction to SPAC6G10.10c Antibody

SPAC6G10.10c encodes a protein implicated in β-1,6-glucan synthesis and cell wall integrity in S. pombe. Polyclonal or monoclonal antibodies targeting this protein are custom-developed for research applications, enabling visualization, quantification, and functional disruption of the protein in yeast models. These antibodies are pivotal for understanding fungal pathogenesis and cell cycle regulation .

Role in Cell Wall Synthesis

• SPAC6G10.10c depletion disrupts β-1,6-glucan polymer formation, leading to cell wall fragility and compromised structural integrity.

• Mutants exhibit malformed septa with aberrant accumulation of β-1,3-glucan, suggesting cross-talk between glucan synthase pathways .

Septation Defects

• Conditional knockdown of SPAC6G10.10c results in incomplete septum closure and abnormal cell morphology.

• Transcriptomic analyses reveal upregulated expression of glucanases (e.g., Gas2p) and other cell wall repair enzymes in response to SPAC6G10.10c deficiency .

Glycosylation Dependencies

• SPAC6G10.10c protein undergoes O-mannosylation, which masks an unconventional N-glycosylation site (N-X-A sequon).

• In O-mannosylation-deficient strains (oma4Δ), N-glycosylation at this site becomes detectable, altering protein stability and function .

Fungal Pathogenesis Studies

• Antibodies against SPAC6G10.10c enable tracking of cell wall synthesis during infection models, aiding antifungal drug discovery.

• Used to validate β-1,6-glucan as a therapeutic target in Candida and Aspergillus species .

Cell Cycle and Septation Analysis

• Immunofluorescence with SPAC6G10.10c antibodies visualizes septum assembly defects in mutants, linking glucan metabolism to cytokinesis .

Glycoengineering

• Facilitates studies on engineered yeast strains with modified glycosylation pathways for biopharmaceutical production .

Technical Considerations

• Cross-Reactivity: Antibodies may recognize homologs in other fungi (e.g., S. cerevisiae Kre9), necessitating validation via knockout controls .

• Storage: Stable at -80°C with carrier proteins (e.g., BSA) to prevent aggregation .

Unresolved Questions and Future Directions

• Mechanistic Role: Precise enzymatic function of SPAC6G10.10c in β-1,6-glucan synthesis remains unclear.

• Therapeutic Potential: Could targeting SPAC6G10.10c enhance antifungal efficacy?
