Tissue specificity
BLK showed its expression in various tissue of human beings such as lymphatic organs, pancreatic islets, Leydig cells, striate ducts of salivary glands and hair follicles etc. GeneCards (Stelzer et al., 2016) used to extract the data of mRNA expression in normal human tissues and found the expression ranges from 2-3. It has been noticed higher expression in blood, retina, spinal cord, liver, lung, Thyroid, Prostrate, Lymph Node.
