Popis

General description

Monoclonal Anti-PSPC1 (mouse IgG1 isotype) is derived from the hybridoma 1L4 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a synthetic peptide corresponding to a sequence at the C-terminal region of mouse PSPC1. DBHS (Drosophila behavior, human splicing) protein family, consisting also of NONO (nonPOU-domain-containing, octamer binding protein) and SFPQ (splicing factor, praline- and glutamine-rich). NONO, paraspeckle component 1 (PSPC1) and SFPQ are the core protein components of paraspeckles. These multi-functional nuclear proteins, under normal conditions, cycle between the nucleoplasm, paraspeckles and the nucleolus.

Paraspeckle component 1 (PSPC1) is encoded by the gene mapped to human chromosome 13q12.11. The encoded protein is a member of DBHS (Drosophila Behavior Human Splicing) family of proteins.

Immunogen

Synthetic peptide corresponding to a sequence at the C-terminal region of mouse PSPC1, conjugated to KLH. ¹ The corresponding sequence is identical in rat and human PSPC1.

Application

Monoclonal Anti-PSPC1 antibody produced in mouse has been used in immunohistochemistry, immunoblotting and immunofluorescence.

Biochem/physiol Actions

Drosophila behavior, human splicing (DBHS) proteins bind both double- and single-stranded DNA and RNA, and are involved in various aspects of RNA and DNA metabolism, such as transcription, pre-mRNA 3′ processing, transcription termination and mRNA splicing. DBHS proteins regulate circadian rhythm and carcinogenesis. PSPC1 activates androgen receptor mediated transcription. PSPC1 forms a heterodimer with NONO that localizes to paraspeckles in a RNA polymerase II-dependent manner.

Since paraspeckle component 1 (PSPC1) has lower background nucleoplasmic signal in various cell types compared to other members of DBHS (Drosophila Behavior Human Splicing) family of proteins, it is frequently used as a marker for paraspeckles. The encoded protein plays a vital role in regulation of transcription. Deletion of the gene is associated with the hindered psychomotor development, muscle hypotonia, unilateral microphthalmia with ptosis, congenital eye malformation and facial dysmorphic features.
