Role of adaptor proteins in secretory granule biogenesis and maturation.

Frontiers in endocrinology

Bonnemaison ML, Eipper BA, Mains RE.
PMID: 23966980
Front Endocrinol (Lausanne). 2013 Aug 14;4:101. doi: 10.3389/fendo.2013.00101. eCollection 2013.

In the regulated secretory pathway, secretory granules (SGs) store peptide hormones that are released on demand. SGs are formed at the trans-Golgi network and must undergo a maturation process to become responsive to secretagogues. The production of mature SGs...

Effects of copper occupancy on the conformational landscape of peptidylglycine α-hydroxylating monooxygenase.

Communications biology

The structures of metalloproteins that use redox-active metals for catalysis are usually exquisitely folded in a way that they are prearranged to accept their metal cofactors. Peptidylglycine α-hydroxylating monooxygenase (PHM) is a dicopper enzyme that catalyzes hydroxylation of the...

PERK-mediated expression of peptidylglycine α-amidating monooxygenase supports angiogenesis in glioblastoma.

Oncogenesis

Soni H, Bode J, Nguyen CDL, Puccio L, Neßling M, Piro RM, Bub J, Phillips E, Ahrends R, Eipper BA, Tews B, Goidts V.
PMID: 32054826
Oncogenesis. 2020 Feb 13;9(2):18. doi: 10.1038/s41389-020-0201-8.

PKR-like kinase (PERK) plays a significant role in inducing angiogenesis in various cancer types including glioblastoma. By proteomics analysis of the conditioned medium from a glioblastoma cell line treated with a PERK inhibitor, we showed that peptidylglycine α-amidating monooxygenase...

Proteases Shape the .

Proteomes

Luxmi R, Blaby-Haas C, Kumar D, Rauniyar N, King SM, Mains RE, Eipper BA.
PMID: 30249063
Proteomes. 2018 Sep 23;6(4). doi: 10.3390/proteomes6040036.

The recent identification of catalytically active peptidylglycine α-amidating monooxygenase (PAM) in Chlamydomonas reinhardtii, a unicellular green alga, suggested the presence of a PAM-like gene and peptidergic signaling in the last eukaryotic common ancestor (LECA). We identified prototypical neuropeptide precursors...

Synaptic plasticity, a symphony in GEF.

ACS chemical neuroscience

Kiraly DD, Eipper-Mains JE, Mains RE, Eipper BA.
PMID: 20543890
ACS Chem Neurosci. 2010 May 19;1(5):348-365. doi: 10.1021/cn100012x.

Dendritic spines are the postsynaptic sites for the majority of excitatory synapses in the mammalian forebrain. While many spines display great stability, others change shape in a matter of seconds to minutes. These rapid alterations in dendritic spine number...
