Several types of targeting probes, such as monoclonal antibodies, their proteolytic and engineered fragments, and scaffold proteins
, were evaluated for imaging of HER2 .
PDZD7 is a scaffold protein
containing three PDZ domains, a HNL domain, and a PR region.
PDZK1, a scaffold protein
, contains four PDZ-banding domains generally comprising 80-90 amino acids, which play crucial roles in targeting proteins to specific cell membranes, assembling proteins into signaling complexes for efficient transduction, and regulating the functions of transmembrane proteins .
Several studies supported that TRB3 may function as a scaffold protein
to control MAPK activity [10, 16, 17].

Homer1b/c links metabotropic glutamate receptor 5 to extracellular signal-regulated protein kinase cascades in neurons," Journal of Neuroscience, vol.
Prior to Amgen, Hayes served as vice president and Venture Leader of Centyrex, a biotech Venture within Janssen R and D, focused on the development of small alternative scaffold proteins
Both IGF signaling and insulin require scaffold proteins
that are the key regulators of many signaling pathways.
Furthermore, high-titer platform technologies for new antibody mimetic formats such as scaffold proteins
and antibody fragments are available for the manufacture of customer products.

It is possible to develop even smaller targeting probes by using engineered nonimmunoglobulin scaffold proteins
, which can be 2- to 4-fold smaller than VHH fragments.
