Abstract: SPINK2 mutant peptide conjugates are provided that inhibit KLK5. The KLK5 inhibitory peptide conjugates are Fc fusion peptides in which, in certain embodiments, the Fc region of the fusion peptides are the Fc region of human IgG1 or a fragment thereof. The KLK5 inhibitory peptide conjugates include an amino acid sequence of one of SEQ ID NOs: 34, 36, 38, 40, 42, 44, 46, 48, 96, 50, 52, 54, 56, 58, or 60. Pharmaceutical compositions that include the KLK5 inhibitory peptide conjugates useful for treating KLK5-related diseases are also provided.

Abstract: It is intended to provide a novel peptide. The present invention provides a peptide which comprises the amino acid sequence shown in SEQ ID NO: 30 and inhibits protease activity.

Abstract: Compositions and methods are provided for the development and screening of antibody-based binding regions (ABR) that mimic T cell receptor specificity (TCRm). The TCRm-ABR of the disclosure are developed to specifically bind to the combination of an MHC antigen and peptide, and to substantially lack binding to the MHC in the absence of the cognate antigen.

Abstract: The present invention provides a novel peptide that has an amino acid sequence represented by SEQ ID NO: 18, and binds to an active protease but does not bind to a pro-protease.
