Product Specifications

Immunogen

Phospho-Profilin (Ser-138) synthetic peptide (coupled to carrier protein) that includes amino acids surrounding Ser-138 in human Profilin 1. This sequence is well conserved in rat and mouse Profilin 1. The serine site has some homology to the conserved site (Ser-138) in Profilin-2a and Profilin-2b, but the site is not conserved in Profiin-3 and Profilin-4. [UniProt# P07737]

Modification

p Ser138

Specificity

This antibody was cross-adsorbed to unphosphorylated Profilin 1 (Ser-138) then affinity purified using Profilin 1 (Ser-138) peptide (without carrier). The antibody detects a 15 kDa band corresponding to the apparent molecular mass of Profilin 1 in human Jurkat and A431 cells, as well as rat PC12 cells. This reactivity is decreased by lambda phosphatase treatment, and is blocked by phospho-profilin (Ser-138) blocking peptide.

Western Blot: Profilin 1 [p Ser138] Antibody [NBP3-23342] -

Western Blot: Profilin 1 [p Ser138] Antibody [NBP3-23342] - Western blot of Jurkat stimulated with calyculin A (100 nM) for 30 min (lanes 1-6). The blots were probed with anti-Profilin (a.a. 132-140) (lanes 1-3) or anti-Profilin (Ser-138) phospho-specific (lanes 4-6). Both antibodies were used in the absence (lanes 1 & 4) or presence of unphosphorylated Profilin (Ser-138) (lanes 2 & 5) or phospho-Profilin (Ser-138) (lanes 3 & 6) blocking peptides.

Background: Profilin 1

Profilin is an ubiquitous small (12-15 kDa) phosphoinositides and poly-L-proline binding protein that plays a role both in signal transduction pathways and actin filament dynamics. There are two mammalian profilins with similar biochemical properties but different expression patterns. Whereas profilin I appears to be highly expressed in most tissues except for skeletal muscle, profilin II is predominantly expressed in brain and at lower levels. It is also in expressed in skeletal muscle, the uterus and kidneys. Profilin is a mainly cytosolic protein with higher concentrations in dynamic membrane areas like the leading edge and ruffling membranes.
