Polo-like kinase 4 (Plk4) is a master regulator of centriole duplication and targets to centrioles through the association of its cryptic polo box domain with centriole receptors. In this issue of Structure, Shimanovskaya and colleagues unveil a new dimeric architecture of Plk4's cryptic polo box that reveals a conserved mechanism for centriole targeting of the kinase.

Cryptococcus gattii consists of four cryptic species, VGI, VGII, VGIII, and VGIV. Herein, a duplex PCR assay using two primer pairs targeting the vacuolar membrane gene and the intergenic spacer region was developed. It successfully distinguished the cryptic species according to the distinct size of the amplicons.

What is cryptic genetic variation? Cryptic genetic variation refers to unexpressed, bottled-up genetic potential. It is not normally seen, but is expressed under abnormal conditions such as in a new environment or a different genetic background. In a sense, the measurable component of normal variation is just the tip of an iceberg of genetic possibilities that are hidden below the visible surface.

Allosteric drugs, which bind to proteins in regions other than their main ligand-binding or active sites, make it possible to target proteins considered "undruggable" and to develop new therapies that circumvent existing resistance. Despite growing interest in allosteric drug discovery, rational design is limited by a lack of sufficient structural information about alternative binding sites in ...

The dystrophin gene, which is mutated in Duchenne muscular dystrophy, is the largest known human gene and characterized by the huge size of its introns. Intron 2 has been shown to include cryptic exons termed exons 2a and 2b, while intron 3 has been shown to include a cryptic exon designated exon 3a. In the present study, we identified 2 and 1 additional cryptic exons in introns 2 and 3, respec...

There are many examples of cryptic species that have been identified through DNA-barcoding or other genetic techniques. There are, however, very few confirmations of cryptic species being reproductively isolated. This study presents one of the few cases of cryptic species that has been confirmed to be reproductively isolated and therefore true species according to the biological species concept...

sequence data of a recent coi barcoding study on fish from the nayband national park in the persian gulf showed relatively high sequence divergence among nominal gerres filamentosus specimens. the sequences grouped into two clusters, signaling the possible existence of cryptic species. the clustering pattern was corroborated by results of 16s rdna sequencing. we investigated the hypothesis that...

Objective The Subtelomeric rearrangements are increasingly being investigated in cases of idiopathic intellectual disabilities (ID) and congenital abnormalities (CA) but have also been suspected to be responsible for unexplained recurrent miscarriage (RM). We have noticed a higher risk of subtelomeric translocations in association with CA and ID. Such rearrangements can go unnoticed through con...
