DESCRIPTION

Also known as TSAP1_HUMAN, TRNAU1AP, SECP43, TRSPAP1. Involved in the early steps of selenocysteine biosynthesis and tRNA(Sec) charging to the later steps resulting in the cotranslational incorporation of selenocysteine into selenoproteins. Stabilizes the SECISBP2, EEFSEC and tRNA(Sec) complex. May be involved in the methylation of tRNA(Sec). Enhances efficiency of selenoproteins synthesis (By similarity). Component of the tRNA(Sec) complex composed at least of EEFSEC, SECISBP2, SEPHS1, SEPSECS, TRNAU1AP and tRNA(Sec). Found in a complex with tRNA(Sec). Interacts with SEPSECS. Associates with mRNP and/or polysomes (By similarity). Found in a complex with EEFSEC, SECISBP2, TRNAU1AP and tRNA(Sec).
