| Note | Must not be confused with CALM1 (calmodulin 1, sitting in 14q24-31), or with neurofibromatosis type 6 (also called CALM, for: cafe au lait spots multiple); therefore the name is likely to change. |
| DNA/RNA |
| Transcription | Major mRNA: 4 kb; other: 3 and 9 kb. |
| Protein |
 | |
| Description | 652 amino acids. |
| Function | Role in the integration of signals from different pathways (clathrin, phosphoinositols, receptor-mediated endocytosis). |
| Homology | With AP3 (Adaptor Related Proteins), a clathrin assembly protein, and SNAP91 (AP180). |
| Implicated in |
| Entity | t(10;11)(p13;q14-21) PICALM / MLLT10 |
| Disease | T-cell acute lymphoblastic leukemia (ALL) mainly; at times acute myeloid leukemia (AML) and/or AML with T-cell markers (Dreyling et al., 1996; Kobayashi et al., 1997). |
| Prognosis | uncertain (median survival 2 yrs?). |
| Cytogenetics | may well be confused with the t(10;11)(p12;q23) , where KMT2A in 11q23 is involved, instead of PICALM |
| Hybrid/Mutated Gene | 5' PICALM - 3' MLLT10 |
| Abnormal Protein | Both PICALM-MLLT10 and the reciprocal MLLT10-PICALM are expressed. |
| Entity | t(11;11)(q14;q23) KMT2A / PICALM |
| Disease | AML and B-cell ALL (Meyer et al., 2013; Wechsler et al., 2003). |
| Hybrid/Mutated Gene | 5' KMT2A - 3' PICALM |
| Abnormal Protein | The KMT2A/PICALM fusion protein was contained 1803 amino acids and included 1406 amino acids from KMT2A A-T hooks and repression domain, and a PICALM-derived clathrin-binding domain in Wechsler et al., 2003. |
