PXMP4 (Peroxisomal Membrane Protein 4), also known as PMP24, is a 24 kDa integral membrane protein localized to peroxisomes. It plays roles in peroxisome biogenesis, fatty acid oxidation, and reactive oxygen species metabolism .
Western Blot: Detects endogenous PXMP4 in human and monkey samples .
Functional Studies: PXMP4 is implicated in peroxisomal disorders and metabolic pathways, though direct studies using this antibody remain limited in published literature.
PMEL (Premelanosome Protein), also called gp100 or PMEL17, is a melanocyte-specific glycoprotein critical for melanosome maturation and amyloid fibril formation. Mutations in PMEL correlate with pigmentation disorders .
Applications: Flow cytometry, immunohistochemistry (IHC), Western blot.
Specificity: Binds PMEL on melanoma cell surfaces without cross-reactivity to GPNMB or LAMP .
Applications: IHC, WB, ELISA.
Specificity: Recognizes melanomas and melanocytic differentiation markers .
Amyloidogenesis: PMEL’s N-terminal region (residues 77–90) is essential for fibril formation. Mutations (e.g., F84A, F90A) disrupt trafficking and fibrillogenesis .
Therapeutic Potential: PMEL is explored as a target for antibody-drug conjugates in pigmentary diseases due to its melanocyte-specific expression .
While "PME24 Antibody" is not a standard designation, the above analysis clarifies two plausible candidates:
Anti-PMP24 (PXMP4): A peroxisomal protein antibody with limited but specific research applications.
Anti-PMEL (gp100): A well-characterized antibody targeting melanosomal pathways, with therapeutic relevance in oncology and dermatology.
