Localization of microtubule-associated protein (MAP) 1B in the postsynaptic densities of the rat cerebral cortex
Open accessAbstract
1. Although microtubule-associated protein (MAP) 1B and its phosphorylation have been suggested to be important for synapse formation among cortical neurons, the localization of MAP1B in synapses has not yet been confirmed. In this report, we examine the localization of MAP1B in synaptic regions. 2. The localization of MAP1B was observed by immunohistochemical and electron microscopic techniques using specific antibodies against MAP1B. 3. MAP1B immunoreactivities were widely distributed in the cerebral cortex and were observed in the postsynaptic area but not in presynaptic terminals. 4. These synapses were classified as the asymmetrical type. 5. Only some synapses exhibited MAP1B immunoreactivities. MAP1B-immunopositive synapses accounted for about half of the total synapses. 6. Such a localization suggests MAP1B's important roles in synaptic functions.

Loss of certain cytoskeletal proteins appears to be a common mechanism in AD, PD, and ALS, whereas AD-specific modules are linked to loss of a select group of microtubule and related proteins represented by hubs MAP1B (E-M10) and DNM3 (E-M20).
“Thus, loss of certain cytoskeletal proteins appears to be a common mechanism in AD, PD, and ALS, whereas AD-specific modules are linked to a loss of a select group of microtubule and related proteins represented respectively by hubs MAP1B (E-M10) and DNM3 (E-M20) (Gray et al., 2003; Kawakami et al., 2003).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
