Function
Integral component of the filamentous matrix of the centrosome involved in the initial establishment of organized microtubule arrays in both mitosis and meiosis. Plays a role, together with DISC1, in the microtubule network formation. Is an integral component of the pericentriolar material (PCM). May play an important role in preventing premature centrosome splitting during interphase by inhibiting NEK2 kinase activity at the centrosome. -
Tissue specificity
Expressed in all tissues tested, including placenta, liver, kidney and thymus. -
Involvement in disease
Microcephalic osteodysplastic primordial dwarfism 2 -
Domain
Composed of a coiled-coil central region flanked by non-helical N- and C-terminals. -
Cellular localization
Cytoplasm > cytoskeleton > microtubule organizing center > centrosome. Centrosomal at all stages of the cell cycle. Remains associated with centrosomes following microtubule depolymerization. Colocalized with DISC1 at the centrosome. - Information by UniProt

Human coronary artery endothelial cells (HCAEC) were labeled for Pericentrin using ab4448 at 1/100 dilution in ICC/IF. Primary incubation was for 1 hour at room temperature (green). The seciondary antibody was a Goat anti-rabbit IgG AlexaFluor® conjugate.
Fixation: Formaldehyde. Permeabilisation: 0.1% Trition X-100 in HBSS.

Centrosomes were stained using anti-pericentrin antibody ab4448 (magenta), nuclear DNA is shown in blue (DAPI).
Statistical methods: Kruskal-Wallis test. Mann-Whitney U tests followed by Bonferroni-Holm p-value correction were made as post-hoc tests in order to compare the MDS and sAML patients with the control group.

The cells were fixed in methanol (5 minutes) and incubated with the antibody (ab4448, 1 µg/ml) for 1 hour at room temperature. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1 hour. Image-iTTM FX Signal Enhancer was used as the primary blocking agent, 5% BSA (in TBS-T) was used for all other blocking steps. DAPI was used to stain the cell nuclei (blue). Alexa Fluor® 594 WGA was used to label plasma membranes (red).

The cells were fixed in 100% methanol for 5 minutes at -20°C and then incubated in 1% BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1 hour at room temperature to permeabilize the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab4448 at 5 µg/ml) overnight at +4°C. The secondary antibody (pseudo-colored green) was Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed (ab150081) used at a 1/1000 dilution for 1 hour at room temperature. Alexa Fluor® 594 WGA was used to label plasma membranes (pseudo-colored red) at a 1/200 dilution for 1 hour at room temperature.
DAPI was used to stain the cell nuclei (pseudo-colored blue) at a concentration of 1.43µM for 1 hour at room temperature.
