Background:
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 (1). TESPA1 encodes a protein of 458 amino acids and is highly conserved among vertebrate species (2). TESPA1 expression was tightly regulated during T cell development, with highest expression at the DP stage (3). TESPA1 deficiency resulted in failure of positive selection and substantially fewer of CD4+ and CD8+ SP cells in the thymus (1,4).
