Tra or TRA may refer to:
Female-specific protein transformer is a protein that in Drosophila melanogaster is encoded by the tra gene.
The transformer protein controls female somatic sexual differentiation.
Trogir (Latin: Tragurium; Italian: Traù; Ancient Greek: Τραγύριον, Tragyrion or Τραγούριον, TragourionTrogkir) is a historic town and harbour on the Adriatic coast in Split-Dalmatia County, Croatia, with a population of 10,818 (2011) and a total municipality population of 13,260 (2011). The historic city of Trogir is situated on a small island between the Croatian mainland and the island of Čiovo. It lies 27 kilometres (17 miles) west of the city of Split.
Since 1997, the historic centre of Trogir has been included in the UNESCO list of World Heritage Sites.
In the 3rd century BC, Tragurion was founded by Greek colonists from the island of Vis, and it developed into a major port until the Roman period. The name comes from the Greek "tragos" (male goat). Similarly, the name of the neighbouring island of Bua comes from the Greek "voua" (herd of cattle). The sudden prosperity of Salona deprived Trogir of its importance. During the migration of Croats the citizens of the destroyed Salona escaped to Trogir. Initially the Roman Tragurium was one of the Dalmatian City-States. From the 9th century on, Trogir paid tribute to Croatian rulers and to the Byzantine empire. The diocese of Trogir was established in the 11th century (abolished in 1828; it is now part of the Roman Catholic Archdiocese of Split-Makarska and has temporarily been a Latin titular bishopric) and in 1107 it was chartered by the Hungarian-Croatian king Coloman, gaining thus its autonomy as a town.
The U.S. Congress passed the Tax Reform Act of 1986 (TRA) (Pub.L. 99–514, 100 Stat. 2085, enacted October 22, 1986) to simplify the income tax code, broaden the tax base and eliminate many tax shelters. Referred to as the second of the two "Reagan tax cuts" (the Kemp-Roth Tax Cut of 1981 being the first), the bill was also officially sponsored by Democrats, Richard Gephardt of Missouri in the House of Representatives and Bill Bradley of New Jersey in the Senate.
The Tax Reform Act of 1986 was given impetus by a detailed tax-simplification proposal from President Reagan's Treasury Department, and was designed to be tax-revenue neutral because Reagan stated that he would veto any bill that was not. Revenue neutrality was targeted by decreasing individual income tax rates, eliminating $30 billion annually in loopholes, while increasing corporate taxes, capital gains taxes, and miscellaneous excises. The act raised overall revenue by $54.9 billion in the first fiscal year after enactment As of 2014, the Tax Reform Act of 1986 was the most recent major simplification of the tax code, drastically reducing the number of deductions and the number of tax brackets (for the individual income tax) to three.
CD46 complement regulatory protein also known as CD46 (cluster of differentiation 46) and Membrane Cofactor Protein is a protein which in humans is encoded by the CD46 gene. CD46 is an inhibitory complement receptor.
This gene is found in a cluster on chromosome 1q32 with other genes encoding structural components of the complement system. At least fourteen different transcript variants encoding fourteen different isoforms have been found for this gene.
The protein encoded by this gene is a type I membrane protein and is a regulatory part of the complement system.
The encoded protein has cofactor activity for inactivation (through cleavage) of complement components C3b and C4b by serum factor I, which protects the host cell from damage by complement.
The protein encoded by this gene may be involved in the fusion of the spermatozoa with the oocyte during fertilization.
The encoded protein can act as a receptor for the Edmonston strain of measles virus,human herpesvirus-6 (HHV-6), and type IV pili of pathogenic Neisseria.
