Characteristics of the Kelch domain containing (KLHDC) subfamily and relationships with diseases

open access: yesFEBS Letters, EarlyView.
The Kelch protein superfamily includes 63 members, with the KLHDC subfamily having 10 proteins. While their functions are not fully understood, recent advances in KLHDC2's structure and role in protein degradation have highlighted its potential for drug development, especially in PROTAC therapies.

The apo LETM1 F‐EF‐hand adopts a closed conformation that underlies a multi‐modal sensory role in mitochondria

open access: yesFEBS Letters, EarlyView.
We present the first solution structure of the Ca2+‐depleted LETM1 F‐EF‐hand through a D676A/N678A Ca2+ binding‐deficient mutant, revealing a closed hydrophobic cleft caused by a unique F1‐helix pivot. The apo LETM1 F‐EF‐hand exhibits regiospecific hot and cold unfolding, sensitivity to physiological pH changes and potential for promiscuous heterotypic

How can we improve problem-solving in undergraduate biology? Applying lessons from 30 years of physics education research [PDF]

open access: yesarXiv, 2012
If students are to successfully grapple with authentic, complex biological problems as scientists and citizens, they need practice solving such problems during their undergraduate years. Physics education researchers have investigated student problem solving for the last three decades.

Fibronectin Contributes To Notochord Intercalation In The Invertebrate Chordate, Ciona Intestinalis [PDF]

open access: yes, 2016
Background: Genomic analysis has upended chordate phylogeny, placing the tunicates as the sister group to the vertebrates. This taxonomic rearrangement raises questions about the emergence of a tunicate/vertebrate ancestor.

Insertion of the FeB cofactor in cNORs lacking metal inserting chaperones

open access: yesFEBS Letters, EarlyView.
Nitric oxide reductase is an enzyme found in the bacterial denitrification pathway. The NOR active site contains a non‐heme iron, often, but not always inserted with the assistance of chaperones. Here, we study the insertion of FeB in the subfamily of cNORs lacking chaperones and found a putative channel, conserved in the family, perhaps enabling the ...

Foundations of biology [PDF]

open access: yesarXiv, 2014
It is often stated that there are no laws in biology, where everything is contingent and could have been otherwise, being solely the result of historical accidents. Furthermore, the customary introduction of fundamental biological entities such as individual organisms, cells, genes, catalysts and motors remains largely descriptive; constructive ...

Genes Classical And Genes Developmental: The Different Uses Of The Gene In Evolutionary Synthesis [PDF]

open access: yes, 2000
Dobzhansky (1964) stated that “Nothing in biology makes sense except in the light of evolution,” and the function of the gene is no exception. The use of genes in population genetics and developmental genetics differs significantly.

Fertilization Narratives In The Art Of Gustav Klimt, Diego Rivera And Frida Kahlo: Repression, Domination And Eros Among Cells [PDF]

open access: yes, 2011
Fertilization narratives are powerful biological stories that can be used for social ends, and 20th-century artists have used fertilization-based imagery to convey political and social ideas.

Structural and mechanistic basis for the regulation of the chloroplast signal recognition particle by (p)ppGpp

open access: yesFEBS Letters, EarlyView.
LHCPs are transported to the thylakoid membrane via the (cp)SRP pathway. This process involves a transit complex of (cp)SRP43, (cp)SRP54 and LHCP, which interacts with (cp)FtsY and Alb3 at the membrane. GTP hydrolysis by (cp)SRP54 and (cp)FtsY triggers complex dissociation.
