TNNC1 and small cell lung carcinoma: For instance, in a study using phospho-tyrosine immunoaffinity beads, cTnC (P63316) was found to be phosphorylated at tyrosine 111 (TnC-Y111-P) in human gastrointestinal cancer tissue, non-small cell lung cancer tissue, B cell lymphoma cell line (OCI-ly18), non-small cell lung cancer cells (NCI-H1650), and pancreatic carcinoma cells (PANC-1) [66].
