The JLP (SPAG9) (N-term) antibody targets the N-terminal region of the JNK-associated leucine zipper protein (JLP), also known as sperm-associated antigen 9 (SPAG9). This scaffold protein plays a critical role in regulating mitogen-activated protein kinase (MAPK) signaling pathways, particularly the c-Jun N-terminal kinase (JNK) and p38 MAPK cascades. These pathways are involved in cellular stress responses, differentiation, apoptosis, and cancer progression. SPAG9/JLP facilitates signal transduction by binding to components of these pathways, including JNK, p38. and motor proteins like kinesin, enabling spatial coordination of signaling events.
The protein is expressed in multiple isoforms and localizes to the cytoplasm, cell membrane, or extracellular space depending on isoform variation and post-translational modifications. Overexpression of SPAG9/JLP has been linked to several cancers, including ovarian, breast, and cervical cancers, where it may promote tumorigenesis and metastasis. The N-terminal region is critical for its scaffolding function, mediating interactions with signaling partners.
The JLP (SPAG9) (N-term) antibody is widely used in research to study the expression, localization, and functional roles of SPAG9/JLP in physiological and pathological contexts. It is validated for applications such as Western blotting, immunohistochemistry, and immunofluorescence. Understanding SPAG9/JLP dynamics provides insights into MAPK pathway regulation and its potential as a therapeutic target in cancer and other diseases.
