Whois & Analysis for tpr.org

Texas Public Radio, or TPR is the on-air name for a group of public radio stations serving south central Texas - including San Antonio and the Texas Hill Country - and the Big Country region of West Central Texas.

All are affiliated with National Public Radio.

San Antonio–New Braunfels is an eight-county metropolitan area in the U.S. state of Texas defined by the Office of Management and Budget (OMB).

Colloquially referred to as, the metropolitan area straddles South Texas and Central Texas and is on the southwestern corner of the Texas Triangle.

The official 2011 U.S. Census estimate showed the metropolitan area's population at 2,194,927—up from a reported 1,711,103 in 2000—making it the 25th largest metropolitan area in the United States.

Austin–Round Rock lies about 80 miles northeast of Greater San Antonio.

The tetratricopeptide repeat (TPR) is a structural motif.

It consists of a degenerate 34 amino acid sequence motif identified in a wide variety of proteins.

It is found in tandem arrays of 3–16 motifs, which form scaffolds to mediate protein–protein interactions and often the assembly of multiprotein complexes.

These alpha-helix pair repeats usually fold together to produce a single, linear solenoid domain called a TPR domain.

Proteins with such domains include the anaphase-promoting complex (APC) subunits cdc16, cdc23 and cdc27, the NADPH oxidase subunit p67-phox, hsp90-binding immunophilins, transcription factors, the PKR protein kinase inhibitor, the major receptor for peroxisomal matrix protein import PEX5 and mitochondrial import proteins.

The Texas Hill Country is a 25-county region of Central Texas and South Texas featuring karst topography and tall rugged hills consisting of thin layers of soil atop limestone or granite.

It also includes the Llano Uplift and the second largest granite dome in the United States, Enchanted Rock.

The Hill Country reaches into portions of the two major metropolitan areas, especially in San Antonio's northern suburbs and the western half of Travis County, ending southwest of Downtown Austin.

The region is the eastern portion of the Edwards Plateau and is bound by the Balcones Fault on the east and the Llano Uplift to the west and north.

The terrain is punctuated by a large number of limestone or granite rocks and boulders and a thin layer of topsoil, which makes the region very dry and prone to flash flooding.

The Texas Hill Country is also home to several native types of vegetation, such as various yucca, prickly pear cactus, cedar scrub, and the dry Southwestern tree known as the Texas live oak.
