O-mannosylation and furin processing are critical maturation events for the KIAA1549 protein implicated in pediatric pilocytic astrocytomas.
The gene fusion KIAA1549::BRAF is a common oncogenic driver in pediatric pilocytic astrocytoma. The chimeric fusion protein that comprises most of the type 1 transmembrane KIAA1549 protein fused in its C-terminal cytosolic domain to the truncated BRAF oncogene without its N-terminal autoinhibitory domains. KIAA1549 has...
