D013213 |
[starch

Starch Phosphorylase
|
D024941 |
[An enzyme of the PHOSPHORYLASES family that catalyzes the degradation of starch, a mixture of unbranched AMYLOSE and branched AMYLOPECTIN compounds. This phosphorylase from plants is the counterpart of GLYCOGEN PHOSPHORYLASE in animals that catalyzes the reaction of inorganic phosphate on the terminal alpha-1,4-glycosidic bond at the non-reducing end of glucans resulting in the release of glucose-1-phosphate.

Stargardt Disease
|
D000080362 |
[A juvenile-onset macular dystrophy characterized by progressive loss of VISUAL ACUITY with normal acuity in peripheral VISUAL FIELDS. Other associated clinical features may include LIPOFUSCIN fundus autofluorescence, atrophy of the RETINAL PIGMENT EPITHELIUM, loss of color vision, PHOTOPHOBIA and PARACENTRAL SCOTOMA. Germline mutations in the ABCA4 gene have been identified in recessive and dominant diseases.

Stathmin
|
D050777 |
[A ubiquitous phosphoprotein that serves as an intracellular substrate for a variety of SIGNAL TRANSDUCTION PATHWAYS. PHOSPHORYLATION of stathmin occurs during CELL CYCLE progression, and stathmin functions as a microtubule-destabilizing protein that promotes MICROTUBULE depolymerization during INTERPHASE and late MITOSIS. Stathmin is expressed at very high levels in a variety of human CANCERS.

Statistics, Nonparametric
|
D018709 |
[A class of statistical methods applicable to a large set of probability distributions used to test for correlation, location, independence, etc. In most nonparametric statistical tests, the original scores or observations are replaced by another variable containing less information. An important class of nonparametric tests employs the ordinal properties of the data. Another class of tests uses information about whether an observation is above or below some fixed value such as the median, and a third class is based on the frequency of the occurrence of runs in the data.
