Description

SAMD1 (sterile alpha motif domain containing 1) is a protein-coding gene located on chromosome 19p13.12. The encoded protein contains a sterile alpha motif (SAM) domain, which is often involved in protein-protein interactions and transcriptional regulation. SAMD1 is implicated in chromatin binding and may function as a transcriptional repressor. Expression data suggest roles in development and cancer, with mutations reported in various malignancies.

Mutation functional classification

Loss of Function (LOF)

Frameshift and nonsense mutations likely lead to loss of SAM domain function and transcriptional repression activity.

Gain of Function (GOF)

Not well characterized; some missense variants may alter protein interactions.

Dominant Negative (DN)

No evidence currently available.

Gene Ontology (GO)

protein binding (GO:0005515) nucleus (GO:0005634)
DNA binding (GO:0003677) • transcription regulatory region DNA binding (GO:0044212)

Pathways

Not assigned to any specific KEGG or Reactome pathway as of current annotation.

Protein Summary

SAMD1 encodes a 456-amino acid protein containing a sterile alpha motif (SAM) domain at the N-terminus. The SAM domain mediates protein-protein interactions and is often found in proteins involved in transcriptional regulation and chromatin remodeling. SAMD1 localizes to the nucleus and can bind DNA, suggesting a role in gene expression control. Structural studies indicate that the SAM domain may form homo-oligomers or interact with other SAM-containing proteins. Post-translational modifications include phosphorylation, which may modulate its activity.
