Abstract
The invention relates to polypeptides and proteins known to function in the autophagy pathway that have novel phosphorylation sites. The invention also relates to antibodies specific to these polypeptides and proteins that are phosphorylated or not phosphorylated at novel phosphorylated sites. The invention also relates to methods of producing these antibodies and use of these antibodies in the treatment of diseases related to autophagocytosis.
Claims19
An isolated autophagy peptide comprising an amino acid sequence selected from the group consisting of sequences set forth in Table 1, wherein the x residue is nonphosphorylated or phosphorylated serine, threonine, or tyrosine, and with the proviso that the peptide is not a full-length autophagy protein.
A method for detecting an autophagy protein or fragment comprising an amino acid sequence set forth in Table 4, wherein the x residue is phosphorylated or nonphosphorylated serine, threonine, or tyrosine in a sample, which method comprises:
- (a) contacting a sample containing or suspected of containing an autophagy protein or fragment comprising the amino acid sequence set forth in Table 4, wherein the x residue is phosphorylated or nonphosphorylated serine, threonine, or tyrosine, with an isolated antibody that specifically binds to an epitope that comprises the amino acid residue x in the amino acid sequence set forth in Table 4, wherein the x residue is phosphorylated or nonphosphorylated serine, threonine, or tyrosine;
- and
- (b) assessing a complex formed between said autophagy protein or fragment, if present in said sample, and said antibody, to determine the presence, absence and/or amount of said autophagy protein or fragment in said sample.
