A recommended positive control is A431 cell lysate.
At least three isoforms TESPA1 are known to exist.
TESPA1 is a critical component of the TCR signalosome and is essential for T cell selection and maturation through the regulation of TCR signaling during T cell development. TESPA1 encodes a protein of 458 amino acids and is highly conserved among vertebrate species. TESPA1 expression was tightly regulated during T cell development, with highest expression at the DP stage. TESPA1 deficiency resulted in failure of positive selection and substantially fewer of CD4+ and CD8+ SP cells in the thymus.
