We conclude that although the use of a specific gene influences the tissue distribution of amyloid, each light chain exhibits one or more determinants of organ-specificity, which originate from somatic mutations and post-translational modifications.
35, 36 During chronic inflammation free radicals and aldehydes are produced which induce gene mutations and post-translational modifications of key cancer-related proteins.
Other classes of alterations including mutations and post-translational modifications occur less frequently (Whang et al, 1998; Verhagen et al, 2006; Yoshimoto et al, 2007, 2008).
We have previously shown that mutations and post-translational modifications resulting in the loss of N17 alpha-helical content result in nuclear accumulation of N17 YFP fusion proteins and of endogenous, full-length huntingtin (3, 4).
We make the simplifying assumption that mutations and post-mortem DNA damage are independent within a fragment, with occurrences depending only on the relative position from the sequence ends.
IMEx-level curation requires the mapping of binding regions, point mutations and post-translational modifications to a specified sequence within a reference protein sequence database, UniProtKB in the case of IntAct.
This multiple alignment allowed us to identify post-H/C divergence mutations and correct them to reflect the ancestral sequences, and to identify and distinguish between potential source-gene mutations and post-insertion mutations in the pseudogenes, as described in the results and discussion section.
Notably, using the present assay and even one experiment with a small number (15 25) of zygotes, researchers and technicians can assess the mutation rate and post-injection embryo survival.
In addition, specific antibodies recognizing Aβ with the Arctic mutation and certain post-translational truncations and modifications, were applied (Table 1).
They include all sources of protein variation, and heres a list: sequence mutations, alternative splicing, and post-translational modifications (PTMs).
There was no significant difference between the total number of mutations identified on the pre and post samples.
