Role Of Endoplasmic Reticulum Resident Proteins In Mediation Of Intrinsic Programmed Cell Death (Apoptosis), Surya Pramila Kilaparty Jul 2016

Role Of Endoplasmic Reticulum Resident Proteins In Mediation Of Intrinsic Programmed Cell Death (Apoptosis), Surya Pramila Kilaparty

Theses and Dissertations

Inositol polyphosphates (InsPs) are signaling molecules that regulate various cellular processes including apoptosis. Among enzymes that metabolize InsPs, Multiple Inositol Polyphosphate Phosphatase1 (Minpp1) is the only enzyme located in the endoplasmic reticulum (ER). It dephosphorylates more phosphorylated InsPs to less phosphorylated InsPs in vitro. Changes in cellular InsPs are known to regulate apoptosis. Minpp1 is a member of the histidine acid phosphatase family of proteins with functional resemblance to phytases found in lower organisms. Its physiological function in higher animals is not clear. Besides its role in dephosphorylating InsPs, it has been shown to have mutase activity. This enzyme is …
