In Silico Computing of the Most Deleterious nsSNPs in HBA1 Gene

PMCID: 4733110
PMID: 26824843
DOI: 10.1371/journal.pone.0147702

[…] structure of hba1 protein were 14.79% intermedia, 38.73% buried residues and 46.48% exposed residues ()., the structural annotations were done by online based server [] and norsp (non-regular secondary structure), which identified 7 disordered regions in hba1 protein. compare to the native structure of hba1 protein, mutant g60v has 9 helixes with methionine and valine […]


Transcytosis in the blood–cerebrospinal fluid barrier of the mouse brain with an engineered receptor/ligand system

PMCID: 4596253
PMID: 26491705
DOI: 10.1038/mtm.2015.37

[…] peptide (rsp) sequences of ngfr were purchased and the bamhi-xhoi fragment was inserted into a plasmid containing a multicloning site (mcs-plasmid). the ngfr open reading frame without the rsp (norsp-δngfr) was pcr amplified from the plasmid δngfr-2a-p47 (ref. ), as a ecori-noti fragment and inserted in the rsp-mcs-plasmid, in the same open reading frame as the rsp. the cohesin open reading […]
