Several colorectal cancers and carcinoids along with few breast, prostate and thyroid cancers exhibited weak to moderate cytoplasmic immunoreactivity, with a granular pattern. Remaining cancer tissues were weakly stained or negative.
A single case of carcinoid showed moderate cytoplasmic positivity. Remaining cancers were in general negative.

Description
Amyloid beta (A4) precursor-like protein 1 (HGNC Symbol)
Entrez gene summary
This gene encodes a member of the highly conserved amyloid precursor protein gene family. The encoded protein is a membrane-associated glycoprotein that is cleaved by secretases in a manner similar to amyloid beta A4 precursor protein cleavage. This cleavage liberates an intracellular cytoplasmic fragment that may act as a transcriptional activator. The encoded protein may also play a role in synaptic maturation during cortical development. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]
