**Key characteristics:**
* The CSTP1 gene is located on chromosome 19p13.3.
* It is a pseudogene, meaning that it is not directly coding for a protein.
* It is expressed in a variety of cell types, including acinar cell of the salivary gland, club cell, stromal cell, basal cell, CD8-positive, alpha-beta T cell, neuron, retinal cone cell, and enterocyte.
* It is significantly expressed in cells of the salivary gland.
**Pathways and functions:**
* CSTP1 is involved in the regulation of epithelial cell growth and differentiation.
* It is a key regulator of the development of the immune system.
* It is expressed in cells that are responsible for the maintenance of epithelial integrity, such as acinar cells and club cells.
* It is also expressed in cells that are involved in the immune response, such as dendritic cells and macrophages.
* CSTP1 is a potential tumor suppressor, and mutations in the gene have been linked to the development of a number of human cancers.
**Clinical significance:**
* Mutations in the CSTP1 gene have been linked to the development of a number of human cancers, including lung cancer, breast cancer, and colon cancer.
* CSTP1 is a potential target for cancer therapy, as it is frequently mutated in cancer cells.
* Studies of CSTP1 have also shown that it can inhibit cancer cell growth in vitro.
