History

Until 1918, the village was part of the Austrian monarchy (Austria side after the compromise of 1867), in the Strakonitz (Strakonice) district, one of the 94 Bezirkshauptmannschaften in Bohemia. A post-office was opened in 1869.

Rab (G-protein)

The Rab family of proteins is a member of the Ras superfamily of monomeric G proteins. Approximately 70 types of Rabs have now been identified in humans. Rab GTPases regulate many steps of membrane traffic, including vesicle formation, vesicle movement along actin and tubulin networks, and membrane fusion. These processes make up the route through which cell surface proteins are trafficked from the Golgi to the plasma membrane and are recycled. Surface protein recycling returns proteins to the surface whose function involves carrying another protein or substance inside the cell, such as the transferrin receptor, or serves as a means of regulating the number of a certain type of protein molecules on the surface.

Function

Rab proteins are peripheral membrane proteins, anchored to a membrane via a lipid group covalently linked to an amino acid. Specifically, Rabs are anchored via prenyl groups on two cysteines in the C-terminus. Rab escort proteins (REPs) deliver newly synthesized and prenylated Rab to its destination membrane by binding the hydrophobic, insoluble prenyl groups and carrying Rab through the cytoplasm. The lipid prenyl groups can then insert into the membrane, anchoring Rab at the cytoplasmic face of a vesicle or the plasma membrane. Because Rab proteins are anchored to the membrane through a flexible C-terminal region, they can be thought of as a 'balloon on a string'.

ʾIʿrab

I‘rāb (إﻋﺮﺍﺏ IPA: [ʔiʕraːb]) is an Arabic term for the system of nominal, adjectival, or verbal suffixes of Classical Arabic. These suffixes are written in fully vocalized Arabic texts, notably the Qur’ān or texts written for children or Arabic learners, and they are articulated when a text is formally read aloud, but they do not survive in any spoken dialect of Arabic. Even in Literary Arabic, these suffixes are often not pronounced in pausa (الوقف al-waqf); i.e. when the word occurs at the end of the sentence, in accordance with certain rules of Arabic pronunciation. (That is, the nunation suffix -n is always dropped at the end of a sentence or line of poetry; the vowel suffix may or may not be, depending on the requirements of metre.) Depending on the knowledge of i‘rāb, some Arabic speakers may omit case endings when reading out in Modern Standard Arabic, thus making it similar to spoken dialects. Many Arabic textbooks for foreigners teach Arabic without a heavy focus on i‘rāb, either omitting the endings altogether or only giving a small introduction. Arabic without case endings may require a different and strict word order, similar to spoken Arabic dialects.
