abstract: |
Mittels ITEM-TWO untersuchte ich, inwieweit eine Tumordiagnostik mit dem anti-HpTGEKP-Antikörper
von Aminosäureaustauschen/Phosphorylierungen im bipolaren Antikörperbindemotiv abhängig
ist. Getestet wurden 15 Peptidsequenzen: Die 10 häufigsten C2H2-Zinkfinger-Linker
und der im Endometriumkarzinom im ZNF331-Gen gehäuft vorkommende H11Y-Austausch, inkl.
Phosphorylierungen. Dabei führte die präzisere Differenzierung von Antikörperbindungen
zur Einteilung in ‚orthodoxe/unorthodoxe‘ Epitop-Paratop-Bindungstypen, was wegweisend
zur Charakterisierung künftiger Antikörperdiagnostika/-therapeutika ist.

I applied ITEM-TWO to investigate whether tumor diagnosis with the anti-HpTGEKP antibody
depended on amino acid exchanges/phosphorylations within its bipolar binding motif.
15 peptides were tested: The 10 most common C2H2 zinc finger linkers and linkers carrying
the H11Y exchange plus phosphorylations, caused by mutation of the ZNF331 gene in
uterine corpus endometrial carcinoma. To reach my goal I needed to further differentiate
specific antibody binding introducing a novel 'orthodox/unorthodox' binding type,
which will improve assessment of future antibody-based diagnostics/therapeutics.
