RGD ID: 2325451
Description: Predicted to enable mRNA base-pairing post-transcriptional repressor activity. Involved in several processes, including negative regulation of osteoblast differentiation; positive regulation of Schwann cell migration; and positive regulation of Schwann cell proliferation. Predicted to be located in synapse. Predicted to be part of RISC complex. Biomarker of breast cancer; diabetes mellitus; hepatocellular carcinoma; and sciatic neuropathy. Human ortholog(s) of this gene implicated in gastrointestinal stromal tumor; hepatocellular carcinoma; and oral squamous cell carcinoma. Orthologous to human MIR221 (microRNA 221); INTERACTS WITH 2-acetamidofluorene; aflatoxin B1; atrazine.
