The PITPNA gene, also known as phosphatidylinositol transfer protein Alpha, is a member of the phosphatidylinositol transfer protein (PITP) family and plays a crucial role in lipid signaling and metabolism. The PITPNA gene is located on chromosome 17p13.3 in humans and chromosome 11 B5 in mice. The protein encoded by PITPNA is expressed in various tissues, with higher levels in the retinal pigment epithelium, parotid gland, pons, and specific regions of the skin and brain. One of the main functions of the PITPNA protein is to bind and transfer phosphatidylinositol (PI) and phosphatidylcholine (PC) between cell membrane compartments. This transport process is essential for the synthesis of phosphoinositides, which are key signaling molecules that regulate various cellular activities, including cell growth, differentiation, and survival.

Research has shown that the PITPNA gene plays an important role in neural development and function. Mutations or defects in this gene have been associated with a variety of neurological diseases. For example, alterations in PITPNA expression can affect synaptic function and plasticity, which can lead to cognitive impairment and neurodegenerative diseases. In addition to its neurological importance, PITPNA has been implicated in other physiological processes. The gene has been observed to be involved in regulating insulin secretion from pancreatic beta cells, highlighting its potential link to metabolic disorders such as diabetes.
