CDH16

Cadherin-16 is a protein that in humans is encoded by the CDH16 gene.

This gene is a member of the cadherin superfamily, genes encoding calcium-dependent, membrane-associated glycoproteins. Mapped to a previously identified cluster of cadherin genes on chromosome 16q22.1, the gene localizes with superfamily members CDH1, CDH3, CDH5, CDH8 and CDH11. The protein consists of an extracellular domain containing 6 cadherin domains, a transmembrane region and a truncated cytoplasmic domain but lacks the prosequence and tripeptide HAV adhesion recognition sequence typical of most classical cadherins. Expression is exclusively in kidney, where the protein functions as the principal mediator of homotypic cellular recognition, playing a role in the morphogenic direction of tissue development.

Cadmium hydride

Cadmium hydride (systematically named cadmium dihydride) is an inorganic compound with the chemical formula (CdH
2)
n (also written as ([CdH
2])
n or CdH
2). It is a solid, known only as a thermally unstable, insoluble white powder.

Nomenclature

The systematic name cadmium dihydride, a valid IUPAC name, is constructed according to the compositional nomenclature. Cadmium dihydride is also used to refer to the related molecular compound dihydridocadmium and its oligomers. Care should be taken to avoid confusing the two compounds.

Cadmium hydride is also used as a compositional IUPAC name for the compound with the chemical formula CdH.

History

In 1950 a research group led by Glenn D. Barbaras, synthesized cadmium hydride for the first time. This reaction sequence consisted of demethylation of dimethylcadmium in diethyl ether at −78 °C, to cadmium hydride.

Chemical properties

Solid cadmium hydride, on the basis of its infrared spectrum, is believed to contain hydrogen-bridge bonds. Other lower metal hydrides polymerize in a similar fashion. Unless cooled below −20 °C (−4 °F), cadmium hydride rapidly decomposes to produce cadmium and hydrogen:
