Mycobacterium tuberculosis (Mtb) continues to define new paradigms of host-pathogen interaction. There are several host proteins known which are regulated by Mtb infection. The proteins which regulate host biological processes like apoptosis, cell processes, stress proteins, metabolic enzymes, etc. are targeted by the pathogens. Mtb proteins interact directly or indirectly with host proteins and play an important role in their persistence and intracellular growth. Mtb is an intracellular pathogen. It remains dormant for years within the host without activating its immune system. Mtb Protein tyrosine kinase (PtkA) regulates host anti-apoptotic protein, metabolic enzymes, and several other proteins that are involved in stress regulation, cell proliferation, protein folding, DNA repair, etc. PtkA regulates other mycobacterial proteins and plays an important role in its growth and survival. Here we summarized the current knowledge of PtkA and reviewed its role in mycobacterial intracellular survival as it regulates several other mycobacterial proteins and host proteins. PtkA regulates PtpA secretion which is essential for mycobacterial virulence and could be used as an attractive drug target.
