Are there any negative allosteric regulators for glycogen phosphorylase?
Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.

Are there any negative allosteric regulators for glycogen phosphorylase?
Glycogenolysis is a process of breakdown of glycogen. Glycogen phosphorylase is an enzyme that initiates the degradation of glycogen.
During glycogenolysis, terminal glucose residue removes as alpha-D-glucose-1-phosphate (G1P) from the nonreducing end. This reaction, called phosphorolysis, is catalyzed by the enzyme Glycogen phosphorylase.
Glycogen phosphorylase attacks exoglycosidic bonds. Pyridoxal phosphate is an essential cofactor in the glycogen phosphorylase reaction. Glycogen phosphorylase acts repetitively on the non-reducing end of glycogen until it reaches a point 4 glucose residues away from an (alpha-1-6) branch point.
AMP act as an allosteric activator of Glycogen phosphorylase.
