Antigen Unmasking Is Required to Clinically Assess Levels and Localisation Patterns of Phospholipase C Zeta in Human Sperm
Kashir, Junaid; Mistry, Bhavesh V.; BuSaleh, Lujain; Nomikos, Michail; Almuqayyil, Sarah; Abu-Dawud, Raed; AlYacoub, Nadya; Hamdan, Hamdan; AlHassan, Saad; Lai, F. Anthony; Assiri, Abdullah M.; Coskun, Serdar... more authors ... less authors ( MDPI , 2023 , Article)Mammalian oocyte activation is initiated by intracellular calcium (Ca2+) oscillations, driven by the testis-specific phospholipase C zeta (PLCζ). Sperm PLCζ analysis represents a diagnostic measure of sperm fertilisation ... -
Arrhythmia-Associated Calmodulin E105A Mutation Alters the Binding Affinity of CaM to a Ryanodine Receptor 2 CaM-Binding Pocket
Thanassoulas, Angelos; Theodoridou, Maria; Barrak, Laila; Riguene, Emna; Alyaarabi, Tamader; Elrayess, Mohamed A.; Lai, F. Anthony; Nomikos, Michail... more authors ... less authors ( MDPI , 2023 , Article)Calmodulin (CaM) is a small, multifunctional calcium (Ca2+)-binding sensor that binds and regulates the open probability of cardiac ryanodine receptor 2 (RyR2) at both low and high cytosolic Ca2+ concentrations. Recent ... -
Divergent Biochemical Properties and Disparate Impact of Arrhythmogenic Calmodulin Mutations on Zebrafish Cardiac Function
Da'as, Sahar I.; Thanassoulas, Angelos; Calver, Brian L.; Saleh, Alaaeldin; Abdelrahman, Doua; Hasan, Waseem; Safieh-Garabedian, Bared; Kontogianni, Iris; Nasrallah, Gheyath K.; Nounesis, George; Lai, F. Anthony; Nomikos, Michail... more authors ... less authors ( John Wiley & Sons , 2024 , Article)Calmodulin (CaM) is a ubiquitous, small cytosolic calcium (Ca2+)-binding sensor that plays a vital role in many cellular processes by binding and regulating the activity of over 300 protein targets. In cardiac muscle, CaM ... -
Editorial: The role of calcium signaling in gametogenesis and early embryogenesis
Kashir, Junaid; Lai, F. Anthony; Nomikos, Michail ( Frontiers Media , 2022 , Other)Calcium homeostasis exerts a profound role in determining the quality of gametogenesis, the resultant efficacy of fertilisation and ultimately the competency of embryogenesis. Perhaps no other single ion plays such a ... -
Life-threatening arrhythmogenic CaM mutations disrupt CaM binding to a distinct RyR2 CaM-binding pocket
Angelos, Thanassoulas; Vassilakopoulou, Vyronia; Calver, Brian L.; Buntwal, Luke; Smith, Adrian; Lai, Christopher; Kontogianni, Iris; Livaniou, Evangelia; Nounesis, George; Lai, F. Anthony; Nomikos, Michail... more authors ... less authors ( Elsevier , 2023 , Article)Calmodulin (CaM) modulates the activity of several proteins that play a key role in excitation-contraction coupling (ECC). In cardiac muscle, the major binding partner of CaM is the type-2 ryanodine receptor (RyR2) and ... -
SPERM FACTORS AND EGG ACTIVATION The structure and function relationship of sperm PLCZ1
Thanassoulas, Angelos; Swann, Karl; Lai, F. Anthony; Nomikos, Michail ( BioScientifica , 2022 , Article Review)In 2002, sperm-specific phospholipase C zeta1 (PLCZ1) was discovered and through these 20 years, it has been established as the predominant sperm oocyte-activating factor. PLCZ1 cRNA expression or direct protein microinjection ...
