Guidance and navigation control (GNC) antibody-like proteins and methods of making and using thereof

Abstract

The application provides multi-specific antibody-like proteins may comprising one or more binding domains including a first binding domain (D1), a second binding domain (D2), a third binding domain (D3), a fourth binding domain (D4), a fifth binding domain (D5), or a sixth binding domain (D6). The multi-specific antibody-like protein disclosed herein may be mono-specific, bi-specific, tri-specific, tetra-specific, penta-specific or hexa-specific. The binding domains such as D1, D2, D3, D4, D5, and D6 may each independently have a binding affinity to specificity against a T cell activating receptor, an immune cell receptor, an immune checkpoint molecule, a co-stimulation factor, a receptor of a leukocyte, a tumor antigen, a tumor associated antigen (TAA), a receptor of a tissue cell, a receptor of a cancer cell, or a combination thereof.
