Microsoft PowerPoint

Microsoft PowerPoint is a slide show presentation program currently developed by Microsoft. PowerPoint initially named "Presenter", was created by Forethought Inc.. Microsoft's version of PowerPoint was officially launched on May 22, 1990, as a part of the Microsoft Office suite. PowerPoint is useful for helping develop the slide-based presentation format, and is currently one of the most commonly-used presentation programs available.

History

Originally designed for the Macintosh computer, the initial release was called "Presenter", developed by Thomas Rudkin and Dennis Austin of Forethought, Inc. In 1987, it was renamed to "PowerPoint" due to problems with trademarks, the idea for the name coming from Robert Gaskins. In August of the same year, Forethought was bought by Microsoft for $14 million USD ($29.2 million in present-day terms), and became Microsoft's Graphics Business Unit, which continued to develop the software further. Microsoft's version of PowerPoint was officially launched on May 22, 1990, the same day that Microsoft released Windows 3.0.

PPT1

Palmitoyl-protein thioesterase 1 (PPT-1), also known as palmitoyl-protein hydrolase 1, is an enzyme that in humans is encoded by the PPT1 gene.

Function

PPT-1 a member of the palmitoyl protein thioesterase family. PPT-1 is a small glycoprotein involved in the catabolism of lipid-modified proteins during lysosomal degradation. This enzyme removes thioester-linked fatty acyl groups such as palmitate from cysteine residues.

Clinical significance

Defects in this gene are a cause of infantile neuronal ceroid lipofuscinosis 1 (CLN1, or INCL) and neuronal ceroid lipofuscinosis 4 (CLN4).
