Sibrotuzumab (BIBH 1) 是一种人源化 IgG1 单克隆抗体，靶向成纤维细胞激活蛋白 (FAP)。Sibrotuzumab 可用于结直肠癌和非小细胞肺癌的研究。

The Staphylococcus aureus transpeptidase Sortase A (SrtA) anchors virulence and colonization-associated surface proteins to the cell wall. SrtA selectively recognizes a C-terminal LPXTG motif. SrtA readily reacts with its native substrate Abz-LPETG-Dap(DNP)-NH2, cleaving it and catalyzing the formation of an amide bond between the carboxyl group of threonine and the amino group of cell-wall crossbridges.

Protein Kinase C Peptide Substrate targets specific cell spacers ina manner that is dependent on second messengers and specific adaptor proteins in response to extracellular signals that activate g protein-coupled receptors, tyrosine Kinase receptors, or tyrosine kinase-coupled receptors.
