Serine and arginine rich splicing factor 1 pseudogene 1 (SRSF1P1)

**Serine and arginine rich splicing factor 1 pseudogene 1 (SRSF1P1)** is annotated as a *pseudogene* and not as a protein-coding gene[1]. It shares sequence similarity with the protein-coding gene *Serine and arginine rich splicing factor 1* (SRSF1), which is a well-characterized splicing factor and known proto-oncogene, but SRSF1P1 itself is not known to have a coding or regulatory role. There is no evidence that SRSF1P1 is a therapeutic target or has established biological, pathological, or pharmacological relevance. Existing resources (such as GeneCards) list SRSF1P1 as "pseudogene" and provide no information on protein, biological functions, drug interactions, or disease roles[1]. Thus, it is not considered a valid molecular target for drug development or experimental modulation. **Note:** If you intended the canonical protein-coding *Serine and arginine rich splicing factor 1* (SRSF1, also known as ASF/SF2), this is a splicing factor with recognized biological and disease roles, but SRSF1P1 is not functionally equivalent nor a relevant target[2][3][4].
