The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/2000 - 1/10000. Detects a band of approximately 270 kDa.
Use a concentration of 2 - 5 µg/ml.
功能Required for centrosome assembly and function. Essential for the correct localization of several centrosomal proteins including CEP250, CETN3, PCNT and NEK2. Required to anchor microtubules to the centrosome. Involved in the biogenesis of cilia.
组织特异性Expressed in blood, bone marrow, breast, lymph node, ovary and thyroid.
疾病相关Defects in PCM1 are a cause of thyroid papillary carcinoma (TPC) [MIM:188550]. TPC is a common tumor of the thyroid that typically arises as an irregular, solid or cystic mass from otherwise normal thyroid tissue. Papillary carcinomas are malignant neoplasm characterized by the formation of numerous, irregular, finger-like projections of fibrous stroma that is covered with a surface layer of neoplastic epithelial cells. Note=A chromosomal aberration involving PCM1 is found in thyroid papillary carcinomas. Translocation t(8;10)(p21.3;q11.2) with RET links the protein kinase domain of RET to the major portion of PCM1. Note=A chromosomal aberration involving PCM1 is found in a variety of hematological malignancies including atypical chronic myeloid leukemia (atypical CML) and T-cell lymphoma. Translocation t(8;9)(p22;p24) with JAK2 links the protein kinase domain of JAK2 to the major portion of PCM1.
序列相似性Belongs to the PCM1 family.
翻译后修饰Phosphorylated upon DNA damage, probably by ATM or ATR.
细胞定位Cytoplasm > cytoskeleton. Cytoplasm > cytoskeleton > centrosome. Cytoplasmic granule. Localizes to cytoplasmic granules which are enriched around the centrosome. This centrosomal enrichment requires microtubules and dynein. The majority of the protein dissociates from the centrosome during metaphase and subsequently localizes to the cleavage site in telophase.
Immunoprecipitation of PCM1 from 1mg HeLa whole cell lysate by 3 ug ab72443 followed by WB (20% of IP loaded):
Lane 1: PCM1 precipitate
Lane 2: Control IgG
For blotting immunoprecipitated PCM1, ab72443 was used at 1 ug/ml.
Detection: Chemiluminescence with an exposure time of 10 seconds.
