Provided herein are, inter alia, compositions and methods for modulating gene expression.

A protein comprising (i) a domain of the Platelet-Derived Growth Factor receptor (PDGFR) and (ii) a domain of the Vascular Endothelial Growth Factor receptor (VEGFR) is provided. In a preferred embodiment, said domain of PDGFR and said domain of VEGFR are attached by a linker consisting of proline, alanine and serine. The domain of PDGFR and said domain of VEGFR can also be attached by a linker consisting of proline and alanine. Compositions comprising the proteins, as well as therapeutic uses thereof are also provided.

Peptides that home, target, migrate to, are directed to, are retained by, or accumulate in and/or bind to the cartilage or kidney of a subject are disclosed. Pharmaceutical compositions and uses for peptides or peptide-active agent complexes comprising such peptides are also disclosed. Such compositions can be formulated for targeted delivery of an active agent to a target region, tissue, structure or cell in the cartilage. Targeted compositions of the disclosure can deliver peptide or peptide-active agent complexes to target regions, tissues, structures, or cells targeted by the peptide.

The present application relates to a recombinant protein comprising a spacer peptide and a recombinant Ganoderma lucidum immunomodulatory protein mutant (rLZ-8 mutant), wherein an amino acid sequence of the rLZ-8 mutant comprises at least one amino acid mutation as compared with an amino acid sequence as shown in SEQ ID NO: 10. The present application further relates to use of the recombinant protein for treating diseases.

Provided herein are compositions and methods for modifying a predetermined nucleic acid sequence. A programmable nucleoprotein molecular complex containing a polypeptide moiety and a specificity conferring nucleic acid (SCNA) which assembles in-vivo, in a target cell, and is capable of interacting with the predetermined target nucleic acid sequence is provided. The programmable nucleoprotein molecular complex is capable of specifically modifying and/or editing a target site within the target nucleic acid sequence and/or modifying the function of the target nucleic acid sequence.
