1. Investigate transcription mechanisms involved in neuron and brain development.

2. Protein engineering to improve gene editing, enzyme function and vaccines.

3. Development of Protein platform for medium scale protein production.

Neuronal development is a complex process involving a myriad of mechanisms. Transcription factors play multiple roles in various stages of neuronal development, and alterations or change in balance of different factors aftect the growth of neurons and ultimately brain function. We are focusing on understanding the molecular functions of DYRK1A, a kinase, which when reduced causes microcephaly and stunted growth. DYRK1A functions in multiple cellular events, including in transcription. We have previously shown that in collaboration with CBP and p300 (Histone acetyl transferases), DYRK1A localizes to promoters and enhancers of specific genes and regulates their expression. Interestingly, mutations in CBP/p300 are associated with microcephaly. Also, we have found that DYRK1A is important for cell size regulation.

Protein engineering – We have established the protein platform in the Institute. We establish protocols for producing proteins and purified them using chromatography. Some examples of proteins we have recently purified - Cas9, ABE8E (base editor), alpha-synuclein, bFGF, PDGF-A, EGF.

We are exploring new approaches for protein/RNA delivery using cell penetrating peptides and virus like particles. We are engineering Cas9 with cell penetrating peptides for cellular delivery without the need for transfection reagents.
