The title of this legal writing is "The Completion of the Crime of Gambling Carried Out by minors based on the law Number 11 of 2012 on the Juvenile Justice system". This type of research is normative legal research. Normative legal research is a research conducted or focusing on norm of positive law in the form of legislation. Legal issues raised is whether the completion of the crime of gambling by children is in conformity with the law Number 11 of 2012 about the juvenile justice system. The purpose of this research is to determine and analyze the completion of the crime of gambling by children under the law of the juvenile justice system. The result showed that the efforts made to prevent criminal acts of a child is an attempt preventive and repressive efforts. Juvenile justice system is closely related to restorative justice. Regarding the obligation to make a diversion conducted by law enforcement officials, in particular under Article 7 and 96 of the law number 11 of 2012 on the Juvenile Justice System

Novel Phosphotidylinositol 4,5-Bisphosphate Binding Sites on Focal Adhesion Kinase
<div><p>Focal adhesion kinase (FAK) is a protein tyrosine kinase that is ubiquitously expressed, recruited to focal adhesions, and engages in a variety of cellular signaling pathways. Diverse cellular responses, such as cell migration, proliferation, and survival, are regulated by FAK. Prior to activation, FAK adopts an autoinhibited conformation in which the FERM domain binds the kinase domain, blocking access to the activation loop and substrate binding site. Activation of FAK occurs through conformational change, and acidic phospholipids such as phosphatidylinositol 4,5-bisphosphate (PIP<sub>2</sub>) are known to facilitate this process. PIP<sub>2</sub> binding alters the autoinhibited conformation of the FERM and kinase domains and subsequently exposes the activation loop to phosphorylation. However, the detailed molecular mechanism of PIP<sub>2</sub> binding and its role in FAK activation remain unclear. In this study, we conducted coarse-grained molecular dynamics simulations to investigate the binding of FAK to PIP<sub>2</sub>. Our simulations identified novel areas of basic residues in the kinase domain of FAK that potentially undergo transient binding to PIP<sub>2</sub> through electrostatic attractions. Our investigation provides a molecular picture of PIP<sub>2</sub>-initiated FAK activation and introduces promising new pathways for future studies of FAK regulation.</p></div

Proteorhodopsin Activation Is Modulated by Dynamic Changes in Internal Hydration
Proteorhodopsin, a member of the
microbial rhodopsin family, is
a seven-transmembrane α-helical protein that functions as a
light-driven proton pump. Understanding the proton-pumping mechanism
of proteorhodopsin requires intimate knowledge of the proton transfer
pathway via complex hydrogen-bonding networks formed by amino acid
residues and internal water molecules. Here we conducted a series
of microsecond time scale molecular dynamics simulations on both the
dark state and the initial photoactivated state of blue proteorhodopsin
to reveal the structural basis for proton transfer with respect to
protein internal hydration. A complex series of dynamic hydrogen-bonding
networks involving water molecules exists, facilitated by water channels
and hydration sites within proteorhodopsin. High levels of hydration
were discovered at each proton transfer siteî—¸the retinal binding
pocket and proton uptake and release sitesî—¸underscoring the
critical participation of water molecules in the proton-pumping mechanism.
Water-bridged interactions and local water channels were also observed
and can potentially mediate long-distance proton transfer between
each site. The most significant phenomenon is after isomerization
of retinal, an increase in water flux occurs that connects the proton
release group, a conserved arginine residue, and the retinal binding
pocket. Our results provide a detailed description of the internal
hydration of the early photointermediates in the proteorhodopsin photocycle
under alkaline pH conditions. These results lay the fundamental groundwork
for understanding the intimate role that hydration plays in the structure–function
relationship underlying the proteorhodopsin proton-pumping mechanism,
as well as providing context for the relationship of hydration in
proteorhodopsin to other microbial retinal proteins
