The present invention includes the disclosure of the hPER2 gene and a mutant of the hPER2 gene that participates in the human circadian biological clock. The product of the mutant hPER2 gene found in some familial advanced sleep phase syndrome patients is hypophosphorylated by casein kinase epsilon due to the serine-to-glycine mutation caused by the point mutation of the genomic sequence. Specifically, this serine-to-glycine mutation affects the casein kinase epsilon binding region of the hPER2 protein, thus blocking the phosphorylation cascade ordinarily caused by the binding of casein kinase epsilon to hPER2.

Vascular endothelial growth factor and type I collagen inducible protein (VCIP), also known as phosphatidic acid phosphatase 2b (PAP2b), was identified in a functional assay of angiogenesis. Previously, VCIP was not known to function as an integrin ligand. The present invention discloses VCIP-derived peptides and proteins act as integrin ligands. Since VCIP-derived peptides or proteins are capable of inhibiting specific cell-cell interactions, such inhibitors of cell-cell interactions would be useful for developing novel therapeutic approaches to treat diseases where these interactions have clear pathological consequences. For example, VCIP / PAP2b can be a novel target for anti-angiogenic, anti-cancer and anti-metastatic therapy.
