Mammalian EAK-7 activates alternative mTOR signaling to regulate cell proliferation and migration. [PDF]

, 2018
Nematode EAK-7 (enhancer-of-akt-1-7) regulates dauer formation and controls life span; however, the function of the human ortholog mammalian EAK-7 (mEAK-7) is unknown.

Systematic Review of the Link Between Oxford MEST-C Classification and Complement Activation in IgA Nephropathy

Kidney International Reports
Introduction: IgA nephropathy's (IgAN’s) MEST-C classification relationship with complement activation is still not fully understood because of limited and conflicting evidence.

A novel assay that characterizes properdin function shows neutrophil-derived properdin has a distinct oligomeric distribution

Frontiers in Immunology, 2023
Properdin acts as an essential positive regulator of the alternative pathway of complement by stabilizing enzymatic convertases. Identical properdin monomers form head-to-tail associations of oligomers in a reported 20:54:26 ratio (most often described ...

Calcium signalling links MYC to NUAK1 [PDF]

, 2018
NUAK1 is a member of the AMPK-related family of kinases. Recent evidence suggests that NUAK1 is an important regulator of cell adhesion and migration, cellular and organismal metabolism, and regulation of TAU stability.

Insights Into Enhanced Complement Activation by Structures of Properdin and Its Complex With the C-Terminal Domain of C3b

Frontiers in Immunology, 2019
Properdin enhances complement-mediated opsonization of targeted cells and particles for immune clearance. Properdin occurs as dimers, trimers and tetramers in human plasma, which recognize C3b-deposited surfaces, promote formation, and prolong the ...

Overactivity of Alternative Pathway Convertases in Patients With Complement-Mediated Renal Diseases

Frontiers in Immunology, 2018
Overactivation of the alternative pathway of the complement system is associated with the renal diseases atypical hemolytic uremic syndrome (aHUS) and C3 glomerulopathy (C3G).

Hijacking Factor H for Complement Immune Evasion

Frontiers in Immunology, 2021
The complement system is an essential player in innate and adaptive immunity. It consists of three pathways (alternative, classical, and lectin) that initiate either spontaneously (alternative) or in response to danger (all pathways). Complement leads to

Alternative final steps in berberine biosynthesis in Coptis japonica cell cultures [PDF]

, 1988
In Coptis japonica cell cultures an alternative pathway has been discovered which leads from (S)-tetrahydrocolumbamine via (S)-canadine to berberine. The two enzymes involved have been partially purified.

Alternative Excision Repair Pathways [PDF]

Cold Spring Harbor Perspectives in Biology, 2013
Alternative excision repair (AER) is a category of excision repair initiated by a single nick, made by an endonuclease, near the site of DNA damage, and followed by excision of the damaged DNA, repair synthesis, and ligation. The ultraviolet (UV) damage endonuclease in fungi and bacteria introduces a nick immediately 5' to various types of UV damage ...
